I sold a website to a member and everything went well and after few days I received a negative feedback and the problem was I forgot a answer a question. so when I resolved the problem he refused to remove the feedback and I had to leave negative for him as well. then he again left negative feedback for the same sale thread without another transaction. I just reported this feedback and still hasn't done anything. could someone tell me is this allowed. am I suppose to leave another negative feedback as well ?
