Their email was designed to look like PayPal and even used their address in San Jose. They told me they saw suspicious activity and there was a charge of $899.99 for bitcoin. It said to call this number to dispute this charge for a refund. They had me download an app. to take control of my computer, so when I questioned why, he started saying it was to get my refund form. When I started to really question who he was, he ended our call. Big time scam!!! I was stupid and now I want them exposed and people warned.
