sorry to hear about your problems Macca but I thought I'd throw this tale in as an example of some GOOD people you meet on ebay.
I recently sold some records on ebay and I managed to send two to the wrong people through sheer stupidity on my part. One cost £50 and the other over £200. The guy expecting the £200+ contacted me understandably upset at getting a totally different record and, I suspect, he thought I might be trying to pull a fast one. I was then bricking it in case the other buyer, who was in Europe, might simply decide to ignore my emails etc. as I hadn't dealt with him before and had no idea whether or not he would just keep the record which would have left me £200+ down with little practical recourse.
Fortunately for me, both buyers were 100% honest, helpful and understanding. I paid them both the postage money to send the records on to the other buyer, both did so and the matter is now settled and they are both now very happy with their purchases. I can't help thinkig it could have so easily gone very wrong (and I'll be super careful in future!) but it did restore my faith in humanity, or at least the soul scene section of it
