CT I have had this happen three different times. This is what I have done in all three cases. File an unpaid item dispute. Click on dispute console in "my ebay" and you will see where to read about it and file. Ebay will send them a gentle reminder to pay and give them x number of days to do so. After that and they do not respond you can close the dispute and get back your final value fees. They get an unpaid item strike and the best part is you can leave them negative feedback but they cant leave any feedback for you.
