You can file the dispute in a week time. (that's the bad point)
However you can relist your item anytime after the auction end.
What you will get is FVF (Final value fee) but you wont get your insertion fee back,
I have lost a lot of money on insertion fee because of non paying bidder. Moreover I always make my listing highlight+feature+else list which cost me about £15-20 for total insertion fee. Then I lost them all! This happens many times to me.
At least you got your FVF back so no worry. Left him negative feedback. Next time watching out your bidders. If any high bidder has bad feedback you can just cancel that bid. however sometimes you cannot really protect your listing from these scums. So just let it happens, lose your fee and relist your item
