Live and learn... I needed a fancy work computer and made the unfortunate decision to purchase a used Surface Pro 4 from an Ebay Dealer... Turns out the unit was a bogus attempt to hide a very badly damaged unit. After almost a month of back and forth with eBay and Paypal, even having Microsoft write a full documented report of the cover-up attempt, I received word this morning that Paypal had sided with the merchant and there would be no return or refund for my $800 purchase. They did say I could appeal, so this evening I went back to the Mircosoft store to meet with the Store Manager to get yet another evaluation of the fraudulent purchase. Only things didn't turn out that way, Mircosoft didn't want to write another evaluation, they had decided they wanted to make things right and refund me the amount this unit cost when it was new...$1250! I said but that's way more than what I paid for the damaged unit, she said I know use it to buy extra protection for your new one ( I bought a brand new one from them for only $899) They even gave me the student discount! Way to go Microsoft! I have learned a lesson never buy anything from Ebay or use Paypal... so much for their buyer's guarantee...
