If they have opened a returns request then you can refuse if you want too
If they open a not as described dispute then you have to accept it back
You send a pre paid label for the return and once you have it back then you refund in full
If you dont and the buyer escalates to ebay then you are forced to refund and pay the fees and get a defect on their account.
Best just to deal with the problem
It all should be done through the resolution centre
