Bought a refurbished computer, doesn't work. Contacted the seller for 2 days. Customer support did contact me. Gave me a URL that didn't work.....to check the computer. 7 day money back guarantee. Well, that is over...they want me to still send the computer back (my cost). They think it's the power supply. Cost of shipping back to them: too much I am sure. Since I payed with PayPal, can I try and get my money back.
