Emailing CS is a waste of time. You just get back a carbon copy "we understand blah blah". You need to actually ring them. Tell them that the feedback left does not apply to your item, as you never sold them a shirt.

With regards to what she said about the DSR's - unfortunately this is true. There is a (known) glitch where the smart-phone user either thinks they are leaving 5 stars, or are told they cant leave stars, and then it records as 1's or 2's.  (Except twice, every single low DSR I have received has been due to smart-phones.......and no, ebay wont do anything about it. Which I believe is morally wrong, as DSR's affect our TRS).

But try ringing CS, and if that doesn't work try again, and so on.......
