I bought a pair of shoes from a seller on Ebay. When I received them they were too big. I decided to re-list them on Ebay, since the listing stated no returns. Since I did not purchase them from the store, I did not want to guarantee they were 100% authentic, which I stated in the auction. I provided pictures of the actual shoes that showed all details. I sold them and the other day I received an email from the buyer stating she wanted a refund because she believes they are fake. She claims that the pictures did not show the actual shoe. I explained to her that in the auction, I stated that I bought these from another seller and that because of that I did not state them as being 100% authentic. I explained that if she had any doubts she should have asked before she placed her bet. She agreed that she should have asked questions about the shoes before placing the bid. I told her that this issue is because of her actions of not asking questions. However, I told her that I would give her a partial refund. She will not accept the refund. What should I do? I do not want to risk getting negative feedback.
