I was also called and told I was being hacked and I was at first ok with paying the fee to fix my computer. After attempting to pay with 3 different  credit cards along with a prepaid card he was not able to complete the transaction. He than asked me to go to western union and not only send the second payment but also include the prepaid visa to a "friend" and not a technician. At this point, i realized something was not right. The names that he gave me,   "Ranveer Singh" & "Abhishek Kumar"
