I just had this very thing happen, from the consumer's side.
I purchased something from an eBay seller in late February, and when it still hadn't arrived after five weeks, I finally contacted the seller. She said she'd check into it, and yesterday she refunded all my money, no questions asked.
It was refreshing after some of the comments in this thread!
