I sold some ELC beauty treatment vouchers. The winning bidder has just emailed me saying that he is very disappointed with the vouchers. He said that the ELC site is no longer available (it is available). He is disgruntled because he paid over the odds for the vouchers. He is also claiming that they aren't complete - he thinks I have used one of the vouchers (I haven't). I sent him all the vouchers that were listed so he knew what he was getting when he bid for them and he says that I haven't presented them nicely, they are just torn out of a book (which they were, but I didn't promise them gift wrapped). I put the ELC website on my listing so he could see for himself the terms and conditions. He is threatening me with negative feedback unless I give him a refund. I have emailed him this morning to offer a full or partial refund as my feedback is important to me. I have less than 15. However, it has been getting at me today. He knew what he was bidding for and that is what he has got. Essentially, I think he is annoyed that he has paid over the odds for this. However, I am annoyed, because the second chance bidder was also bidding over the odds so I have lost out. Do you think I should offer a full or partial refund.
