My brother sold two items and the money was sent to an incorrect email address which is active.

My brother had never owned this address and can not get his money back. PayPal and ebay say it's the others fault. It's been 2 months now back and to with still no answer. 

He had sold things before and after ok. It was during the change with payments via PayPal. 

Any ideas what we do.
