I purchased a computer through a Sears Marketplace vendor, ANTONLINE.com. It came with Windows 7 instead of Windows 10. Since I can no longer get a 10 upgrade for free, I need to shell out $120 in order to upgrade and transfer my old PC files (Windows 10) to the new HP. I have contacted both Sears and ANTONLINE.com. Sears told me ANTONLINE.com would call me in 48 hours. They didn't, I have contacted them by phone and emaii and no way to get a response back. Their reviews for customer support are awful. Is this a certified reseller for HP?
