Next time you get a call from these clowns screw with them. When they say they are receiving reports of your computer having problems tell them good you like having problems with your PC and you hope it infects theirs. Tell them its working like a Swiss watch and you don't care if its creating problems. Then tell them to check this website to see what others say about their scam. Just demoralize them.
I got my first call from 657-235-9124 on September 10, 2015 at 9:38 am. I got up to answer the phone and the caller hung up after only three rings. My caller ID said "John Ciza." I have been on the Do Not Call list for ten years.
laughing so hard _ have worked in IT for 20 years - this guys tried to pull the scam on me - he even called back when I hung up... I told him I worked in IT told him the company I worked for etc and he tried to inform me that Microsoft does not own windows... crickets
