After 2 months of fighting with a seller that sold me blacklisted keys I lodged it with the resolution team, PayPal in there wisdom's are siding with the seller even after providing screenshots of the errors. The reasoning, the product was delivered, well not much good to me if it doesn't work. I thought I was getting buyers protection using PayPal sadly it seems I'm mistaken. You pay transaction fees and a higher exchange rate compared to my bank. But I was ok with that, thinking that I had buyers protection. Buyers beware, Paypal doesn't help protect your against all fraudulent sellers.
