Net a porter is a high end designer online store, so not unreasonable to expect excellent customer service. Absolutely not the case here. They are happy to sell stuff to the customer, that is not a problem, but try returning it for a refund is where the trouble starts. They are uncommunicative, and totally incompetent when you ring to enquire after a week why your refund status is not showing on your account or even that the item has returned to the warehouse. The agents x3 all promise faithfully to look into, escalate and investigate what is going on and assure you that they will prioritise your concerns and email you back. Non of this happens. If you go to Trustpilot their negative 1* reviews now outweigh their positive ones. Avoid them at all costs or if you are in the same situation as myself, still waiting for some communication after 2wks about a refund, start a case with Resolver or the Trading Standards Ombudsman or a chargeback claim.
If you want an online designer retailer who are efficient and have got their act together, look no further than MATCHES- don't use this bunch of cowboys.
