I spoke to Karl Davies today to upgrade my mobile. He was very helpful and knew what he was talking about. Made the process very easy.

Keep away from these as they are shocking for miss selling and just want to tie you up in a long contract and charge obscene amounts of money to get out of it.
Bad customers skills and not even cheap deals AVOID THEM

I'm happy with Onecom. They've offered me some nice deals over the four or so years I've been with them. As market rates tend to fall towards the end of contracts their tariffs look just a little less attractive. That's probably true for most people on longer fixes. But, Onecom insert a review towards the end, which tends to level the playing field. Its good to be able to speak to a real person when needed. My very 1st contact with them and their account management was really winning. Longer term its been pretty good as well.

They are brokers don't own any network. ONECOM to be avoided sell phone and internet contracts you could take directly with the companies in question such a Vodafone. With onecom to be avoided you end up paying a much expensive internet and mobile phone services to cover their commission. ONECOM to be avoided will convince you that by signing up for a three years contract you will save loads of money NOT TRUE. Stay away from ONECON, that's what they are.

WARNING: Get everything in writing before you agree to anything or this company will hoodwink you without a second thought. DO NOT AGREE TO ANYTHING ON THE PHONE. This company is merciless with regard to your personal circumstances and they will use the no cooling off period business to business clause. Shocking business practices, even more so in a time of global pandemic.

Lovely helpful staff who work really hard to resolve my issues. The only reason it's not 5 stars is some technical difficulties with the original call being dropped, but my operative still managed to sort everything and phone me back

1 star is too high!
Fraudulent company who took advantage!
Cancelled a phone contract on behalf of my father who was and still is very ill. Contract was cancelled in writing 5 years ago and they claim never to have received said letter. Blamed my father for not checking that the billing was cancelled whilst in and out of hospital!
Also claiming contract was renewed even though sim and phone was disposed of the same year letter was written...
Then speaking with them today lied in the transcripts about what had been said!
Do not trust or get involved with this bunch of scammers...
Lets see what the complaints manager has to say...

From the very start of my dealings with Onecom - 18 months ago - what they were offering was very confused - what I later called "smoke and mirrors". What they promised me never transpired and they fall back on a contract which descended on me with all sorts of other rubbish. They were difficult, at the start, about allowing my wife's phone to go on the account, apparently due to credit issues - but there aren't any. There have been several occasions when calls and texts which were supposed to be free were invoiced: just a few pounds each time, so more of an irritant value. I chased them on the basis that this might stop it happening again. It hasn't

Finally, I found out that after 17 months the monthly credit, worth half the amount I was invoiced each month by Vodafone, had stopped. With 19 months left to run, I was left with a really unattractive deal. Yes, this was part of the contract, but the sales person who I dealt with NEVER mentioned that it would ever stop, she just kept talking about the net monthly cost as if it would go on forever. I negotiated the best deal I could but it's still more than I would have accepted if this had been made clear at the start.

Onecom are notorious for misselling and dubious sales practices. They should be avoided at all costs. Be extremely careful if you do agree terms with them. Avoid.

After several pressurised phone calls I agreed to switching my service I then had a letter from my what I thought was my old provider stating they were going to charge me just under £35 for my internet to continue. I rang T T. They said I was also having the internet with them at no time did they mention on the telephone that they were not giving me the complete change over I assumed they were, I was told several times that they were going to save me money( not happened.) Also I was not told anything about the term of the contract until a letter arrived, I have requested them to listen to my phone calls all I get is we are looking into it, My husband has Cancer I am very worried about this if it is not resolved soon I will cancel my D. Debit and lket them take me to court if this is the only way to let people know about them. If in the mead time they come up trumps I will post on this review site again.

After having dealt with Karl Davies yesterday initially, and again today, I have to highly commend this young man, to his people skills. He listened, explained and found for me a suitable new package for me. As well as fulfilling these requirements, he was chatty, pleasant and genuinely a breath of fresh air to deal with. So much so will ask for him by name if I need any information in future regarding my contract.
Thank you so much, and to your boss, he is a credit to the company.

Patricia Henry, Happy customer.

SCAM!
Beware if you deal with this company. I was cold-called and told that we could have new phones and reduce our monthly costs. We listened to the the deal. It came out at slightly higher than the the deal we were on but with the discount of £70 each month, it would be a decent reduction. All benefits were explained in detail. What was not explained in detail was the £70 discount was for a limited time of the contract. After the discount period my bill would be much higher for a further two full years with no getout. At the time I asked the question directly, "Will this discount be for all the time we are with Vodaphone?" The question was skirted around with the answer "you can review your contract in 24 months and save even more money". This is classic mis-selling tactic, add in the fact you get no written contract to read or sign shows what type of company you are dealing with. I don't believe any of the five star reviews on this site are genuine.

Used to be good but after a restructure the customer service nose dived! Avoid unless you like stress!

Got hooked into a 36month Business Contract and given bad advice about terminating my existing contract early. No way to terminate early or cancel like a personal contract. Cost me. Thousands of £. Will never use them again or recommend them.

Have been dealing with Onecom ever since they took over Vodafone contracts and have to say they have always been great. All the agents I've spoken to, each year I've renegotiated my contract, have been really helpful. Upgraded my current contract today with Karl Davies who went out of his way to get me a fantastic deal. He was not only friendly and polite but very patient and proactive when I pushed for the better deal!

They kept sending my phone to the wrong address then sent me a bill for the full contract when I cancelled.

I was experiencing network connectivity issues with a new phone I had purchased. I used the online live chat and explained the situation to service advisor who came back to me very quickly with a few possible solutions. Instruction/feedback was clear and simple which helped me understand what to do and I was able to resolve the matter swiftly, thanks to the help of the advisor. This was a much more time-effective method than phoning the customer care line which was my original pursuit. Thanks to the advisor for the help, much appreciated!

In short, after a cold call that sounded too good to be true, I told them what I wanted and could afford and they changed things covertly leading me to believe I would be paying a certain amount. Even though asking multiple times they cleverly manipulated me into the contract with no cool down period. They recorded calls without letting me know(which I now have a copy of for evidence). The said I was entitled to stuff that wasn't available anymore and I am set to pay a lot more money than agreed. Their customer services and care is vague and never answers your questions properly deflecting questions. DO NOT trust this company. I have an official complaint logged with ofcom/Cisas, and even though I know I will win I will waste a lot more time on this dis-honest company. Please avoid. I am also expecting a 'I am sorry yo are unhappy, email us' response even though they have not helped at all every time I have asked.

What sort of buisness put you in 3 year £40 sim only contract on a buisness rate when you're not even a buisness

Avoid like the plague. Transferred out Vodafone direct contract without permission, conned my elderly mother into a sim only contract with no insurance for the same price as our original fully covered policy with free upgrade, finally now to be told contract has been switched back to vodafone, go into Vodafone shop and guess what, still with onecom, and their customer service isn't available at weekends to sort it out.

I contacted OneCom regarding my new mobile telephone and other gadgets via 'online chat'. The person who dealt with me, Eurika, was first class. She dealt with me regarding my queries very quickly, comprehensively and, above all, clearly in a language I could understand. Eurika covered all my points and everything is working as it should thanks to her help. An excellent service, thank you, Eurika.

I Just wanted to say thanks to Kirsty J. From Onecom Who just sorted my problems out super quick! Many thanks you are a star and my mini sim is on its way!
Having been to the Vodafone store who failed, it was a pure joy to get sorted in mega fast time.
Thanks again.

I've been a Vodafone customer for 25 years and Onecom now handle the account. There has obviously been a change of management, as they now resort to using devious deception to make sales, and tell outright lies about getting things sorted. They have owed me £700 + for some time now, after lying to me repeatedly about my contract. They have avoided sending me the copy of the sales conversation which will clearly prove my case. They agreed to pay the refund, but guess what... they never do. Avoid these people they cannot be trusted.
