Blocked my computer, I called, they scanned my computer and called me back on what they said was a secured line. 717-312-4488, 860-756-5210. He said my internet was hacked and anything using internet had to be turned off. Scan revealed that China had charged 8500 to my credit card , transferred me to discover, had the teleprompters etc.... asked me to get visa gift cards in that amount so a duplicate charge could be attempted and then they could reverse both charges....I hung up.... called discover it was all a lie
