Sorry about your situation. Sure it happens quite a lot because ebay totally sucks when it comes to returns...or order cancellations.

Not trying to hijack the thread, but I recently had issue with ebay seller "motorcitymusclecar"... I ordered a complete emergency brake cable kit from them. It wasn't 5 minutes later i realized that i was needing other parts that they offer as well and i wanted to cancel the order and reorder to have all items shipped at once. They refused to cancel the order 5 minutes later because "the order has been processed and shipped"...got that actual response from them. The greedy idiots lost about another $150 in sales, and that will be the last order they receive from me...not that it would hurt their business any.

Buy parts through Amazon. No questions asked on returns. That has happened only once for me, and had no problems getting it done.
