What happens when someone files an unauthorised transaction case against you on Paypal? I sold a Ted Baker phone case my partner bought in error on eBay well over a month ago now just before Christmas, I just happened to be going on PayPal to check for something and noticed a case had been opened on the 26th of this month claiming that the purchase was an 'unauthorised transaction' It was just under £20 so not something you'd necessarily forget about and tracking suggests it arrived just before Christmas. The buyer on eBay appears to be a female but paid through her husband (I presume because of name) Paypal account... I've provided the tracking information with her name and the details but surely they can't hold me liable for something like this...? It may be she used his account without his knowledge and now he's chasing something he thinks is suspicious?
