I purchased a faulty tooky t86 from this website.
I sent it back via standard post for repair to the address they provided me with, and kept the receipt. I did not send it via tracked post because the cost of doing so would exceed the cost of the phone itself.
Of course, Buyincoins claims to never have received the phone. I opened a case with New Zealand post, who sent not one, but two letters to the address Buyincoins originally provided to verify their address, and gain confirmation from them that the item never arrived. Of course, Buyincoins claims neither of them arrived either.
Hence, they have both my money and the phone and I have been emailing them consistently, even sending them a photo of the receipt to prove that the parcel was in fact sent. I have received a mixture of "Claim a refund from your post office" which cannot happen unless they respond to the two letters sent to them by NZ post) which I have explained to them, and "we can only refund you once we receive your parcel"
Which, of course, they are unlikely to admit receiving.
Avoid this website at all costs - or at the very least ensure you pay with Paypal so if something goes wrong you are able to claim back your money!
