That was one side of the story, here is another one.
One of the first questions I have asked amiq was if I could pay by a bank transfer and I have received a confirmation that "bank transfer is fine". When amiq has received a parcel from CPC, he has, for the first time, asked me "Are you able to pay using paypal?" to which I have replied that I specifically asked if bank transfer is fine and that I want to pay using this method. Then I was told that "If you want to pay by bank transfer I'll need your address and phone number" (my actual address, not the one used for parcel forwarding services). Again, this was told to me only after the order was received. I must say, that I have asked his bank account number right after he has placed the order so that I could pay him in front, but he did not provide it. Maybe at that time he already knew that he no longer wants to accept bank transfer or that he would introduce extra requirements that were not agreed on. I have replied that I am not willing to give up the details he has requested as they are not required to make a bank transfer and that there was no mutual agreement that I will do so. I have also said that even if I did provide those details he had no means to verify if they are valid and actually mine, so what is the point of that? I could speculate that even having my details he would not be completely satisfied and ask for some other proof of my identity, for example to provide a photocopy of my passport. He gave me one day to change my mind and has not explained why there was such a change in his requirements. To sum up, we agreed that payment will be made by a bank transfer, he knew that parcel will be shipped to the UK address (to parcel forwarding service), after he has received a parcel he unilaterally introduced new requirements that we did not agreed on and he gave me one day to change my mind and do what he says or otherwise he will return the parcel back to CPC.
I have learned a very good lesson. I should have listened to bd139 much more carefully and just order from other place.
