Shit Jersey on eBay - advice please

Blimey, if I buy a couple of cheapo t-shirts from Camden and they subsequently fall to bits after a couple of washes, mea culpa. Vintage gear / caveat emptor.

For what it's worth, I've bought plenty of stuff of these guys and it has all been good and delivered quickly without problems.

Can't understand why you'd start an internet vendetta against an independent business for the sake of a tenner! Sorry if that sounds harsh.
Thats not the point, its how unhelpful and incredibly rude hes been to me. .
