Yeah I've been through it before. 4 days until you can open an unpaid item case, then 4 days until it can close, so 8 days total.
I'll probably just list them again instead of doing a 2nd chance offer to the next highest bidder.
And what really irks me is its a user with their own store with high feedback, I'm sure they would be pissed if it happened to them, yet they are stiffing me. Some people.
