I got a surface pro 2 off Ebay and it arrived with all the old users data on it. He has an account on the tablet and has a password. I have tried resetting the tablet but I cannot as it keeps asking for recovery media which I do not have. I have attempted to contact the seller and even opened a sales dispute because the seller will not answer me. I am desperate for a solution or anyway I can make this tablet useable. All I have is the tablet, charger, and a keyboard cover. Please help.
