Scammers claiming to be windows technical assistance saying they have received several messages from my computer with errors and viruses. I knew these people were not legit because Microsoft does not call anyone. They tried to give me a false computer windows id of my computer but I was on to them. Anyway I kept them on the phone for a long time wasting their time. Anyway, I asked them what is their contact number and they gave me 800-453-1210 which is in Utah but the caller said they were calling from Denver Colorado. The caller ID said it was 408-152-6459. Well when I called that number I got a local person on the phone, XXX-408-1526 a portion of that number was his. So the scammers have figured out a way to use another number by adding more numbers to it.
