This may well sound pathetic as it is a relatively small amount of money, but it has really bloody annoyed me.
I ordered a DVD for DSD's birthday a month ago. It arrived two weeks after I paid for it, not brilliant service, but that would've been okay had the DVD not been an obvious fake, blank disc, photocopied cover and labelled NTSC, so not the official UK copy the seller had advertised.
I contacted the seller, who said to return it for a refund. So I duly sent it back, and they stopped responding to any messages.
I then got an email from eBay telling me that this seller had been removed from eBay. So I now can't contact them, leave them feedback or in any other way retrieve my money. If I open a PayPal claim, they want tracking details of the package, which I can't give because I already returned it.
I know there's nothing I can do, and let's face it, it's only about a tenner. It's more the fact that this arsehat has taken money, had the disc back and I have pay that money out again to replace DSD's gift. Just a little tale of warning that even though the feedback rules have changed, there are still sellers that take the piss, not just buyers.
