If you get these calls on a cell...send them cell to land line text messages.  They will probably stop calling.  I've had luck doing this.

I just recieved a call from this 706-229-8665, the man with a foreign accent said he was from microsoft & that my computer was infected with viruses & wanted me to do some stuff to my computer.  I REFUSED GIVING ANY INFORMATION......I SAID GIVE ME A NUMBER TO CALL BACK, HE GAVE ME 347-474-0448.  I GOOGLED  BOTH NUMBERS & GATHERED INFORMATION THESE FOREIGNERS ARE SCAMMERS.   I THEN CONTACTED MICROSOFT CORPORATION AT 800+642-7676 & SPOKE TO THERE REPERSENITIVE & WAS TOLD THESE PEOPLE ARE DEFINTLY SCAM ARTIST AND THAT MICROSOFT WOULD NEVER CONTACT ANYONE BY PHONE UNLESS THE CONSUMER CONTACTS MICROSOFT THEMSELVES................***************SO BE AWARE THESE PEOPLE ARE BIG TIME SCAMMERS***********

Mine was about getting a $100 Wal-Mart gift card voucher. Then I quit answering her as if we had been disconnected. It was fun hearing her try to get my attention. After about 3 minutes I finally spoke and told her I was not interested.

Got a call from some guy with a thick Indian accent. Said he was from "tech support" and he was "receiving errors from my computer." I laughed so hard I think I may have hurt his ears! Anyway, hang up on these idiots or do something creative to annoy them or waste their time. They are obviously trying to get people to infect their own computers with malware or something underhanded like that.

I have received 4 calls total from this number, when I answer and say hello its dead and I get disconnected. When I call the number back it claims I have a 100.00 gift card for target or walmart and press 1 to collect it... then it places me on hold. I hung up and I'm not going to waste anymore of my time. Got to love scam artists!! NOT!
