They called saying there was a problem with my windows PC. I verified with my wife that this was not true, realized this was not a 1-800 number, and proceeded to yell at them where they turned around and began yelling back which is another instance i knew this to be a fake because real tech support does not yell at the customer, they hang up on you.
I just got a call from this number but didn't answer. I've been getting a lot of calls lately. Do not call list is worthless because they don't do anything unless they have a ton of complaints and these people use different numbers. I just ordered a TeleZapper from Ebay for $20.00 but haven't received it yet. I had on years ago and they work well. You plug it into your phone line and when you or your answering machine pick up it sends out 3 tones that tell the computer they have dialed a non-working number and takes your number off their list. I've read that the telezapper may not work it voice mail answers but I had to get an answering machine because my voice mail wasn't always notifying me of messages. Technology! One other thing I have done to these people is get a whistle and blow it as loud as I can.
