The issue with appealing any decision for a refund for item not as described, is that eBay do not see the item in question.
I've looked at your items presuming it's not the ones sold on the 1st as these would not have been received, the ones sold around 25th / 26th May most are listed as near mint but one is listed as poor/ Heavily played, is it this one in question?
You haven't described the faults at all in the description box, just Condition is marked as Poor, and I'm afraid the 2 photos do not show any faults which needed to be described. This is probably why eBay have decided against your appeal ?
