Not a complaint about other eBay members this time, just a tidbit for those who feel uncertain or intimidated at the prospect of pushing eBay CS around a bit when necessary:
I had a seller defect due to shipping time on an item that took like two weeks to arrive... no complaint from buyer, in fact they had left positive feedback and I never thought twice about it. Called eBay CS when I found the defect, though, and had to be transferred three different times, verifying my info and explaining to some degree the issue each time, before I finally got someone who could theoretically help ("escalations" department seems the general go-to when you need more than the typical BS responses).
As he investigated the sale date, date the label was printed, and date first scanned, he started right in on the canned response about verified tracking scans and handling times that amounts to "sorry, tough luck, not going to provide any service to you". I flat out interrupted him and said "Let me point out that I live in Texas, and the first tracking scan for this item was several days after the sale... in San Francisco. The buyer lives in New York.. There's no way you can hold me responsible for a delay due to USPS mis-routing the package." After several seconds of silence, his tone of voice totally changed and he went with "OK, it looks like we are going to be able to remove this defect for you..." along with the in depth explanation of how that process works.
It is often a simple battle of wills... but technique goes a long way, too.
