I've added her to my blocked bidders. I guess its just one of those things. 99% of the polpulation are good and honest. Most of the time things go well. Just occassionally we cross paths with the 1%. Can't let it cloud dealings with the 99%.
I left feedback when she paid promptly. Sellers can only leave positive or no feedback. We do have a report a buyer feature though.
Even though I'm behaving like a complete amateur by having a whinge on here, I'm now trading on eBay as a business seller so have to accept returns. Its the first thing I've found that has the potential to break the roof of the carers allowance/ tax credits financial trap and still enable me to be carer for my Autistic eldest (no childcare options available).
We have found that the best way to deal with returns is to refund immediately and politely otherwise it annoys us so much! It is a very low percentage of buyers who misuse the system and we have found that those who ask for a refund because of non-delivery usually offer to repay. We sell on ebay for exactly the same reasons as you!!
You can report the buyer to ebay after the transaction for abusing the returns process. (I think it's on the dropdown menu on the right on the transaction) The buyer wont know about this but Ebay will keep a note on her records - i think if they have a lot of these 'strikes' then eBay will stop their account. I had to do this recently when I reluctantly had to refund for a watch even though the buyer hadnt returned the box and flatly refused to acknowledge receipt of the box!!
