Same as others, sometimes I mess with them and keep them busy as long as possible and others I just tell them I do not even have a computer, they are simply scam fools.
I just got a call from this number and the guy claimed to be calling from 'Windows' help centre because my computer kept sending error reports. I said I wasn't getting error reports, or sending them to Microsoft. I asked how he got my number and he said they got it from following my IP address. I told him that was not acceptable and I was upset they did this and that I was ending the call and hanging up. He yelled at me then told me to go to hell! I'm more than a little freaked out.
Called at 7:25 am. Ringing non-stop. Lucky me, I have caller ID and I do not pick up the phone from a 206 area code since I do not know anybody with this number
