If you can work something out with the vendor outside of the resolution center and they refund you that way, then it doesn't count against your stats. That's not very likely to happen though. If you get a refund through the resolution center, then it will increase your refund rate which, in some cases, becomes an issue for some vendors. The only time a refund does NOT count against your stats is if the vendor has already been banned and you remained in escrow.
