Once I got an item I sold on eBay returned to me through UPS (guy said it wasn't working...I got it back and it worked fine. oh well...) and they charged me $40 in brokerage fees. I refused to pay it, (I mean, it's a RETURN!) and they got a collection agency after me!! So after maybe a 6 months and 6 calls later I caved and paid it. Man, I've never used UPS since.
