eBay

I have test promoted vs unprompted some items have been listed for months and I’m still getting more views on unprompted items. Help me understand why

A buyer refuses to return item and eBay grants him the refund and I have to pay and he get to keep item. This will tally a very big $ tag. It’s not at all fair eBay received proof item was in good condition.

Why is it I buy items anywhere in the world I have no tracking problems. Every other item I purchase off of here I can’t track.
