Hi I have sold an item on Ebay and the buyer has not paid after 9 days. I've sent two invoices and just sent them an email saying If I don't hear anything by friday I will open an unpaid item case. The problem with this is, as far as I understand, If they then pay they can leave me neg feedback in retaliation. The other option seems to be for me to cancel the sale, which I believe would give me a defect. Question is, what is the best option here? I have no negs and the buyer has no buying related negs that I can see. 1 neg as a seller. Do I eat the final value fee and take a defect and relist or file a case and be open to a neg if they are 'forced' to pay? Which would be more detrimental to me as a seller?
