[quote name='Zaku77']I'm a dick, so I would leave neutral. It was 100% the fault of the seller that you are having an issue with your purchase. The fact that you need to pursue it any more than just buying it means that you did not have a positive experience.[/QUOTE]
There were some policy changes on eBay that basically made it so any seller who got a neutral/negative under some conditions could get it removed without any questions. The buyer needs to contact the seller and give them a chance to fix it first. If they don't, then OP can leave whatever he/she wants.
Basically, this lets OP get screwed. If the seller says they'll accept the return, then the buyer is left with the return shipping cost... even though it's not their fault.
