On or about March 25 2020 I called Geeks on Site (Yellow Pages San Francisco, CA tel: 415-275-3323) about a computer problem. I was told to go my computer and follow their instructions. I did this and shortly after they locked my computer and a voice said they found a virus and I had to pay $299.00. I refused and asked they unlock my computer but they hung up. They did not unlock my computer.
