Yes, I've had those too. The one that seems to come from Microsoft and wanting to help me "clean" up my computer to get rid of the virus is the one that I have the most fun with. When they call, and they always seem to have an East Indian accent, I go along with it for a bit but when they want me to turn on my computer, I tell them that I'm away from it and could they call tomorrow morning around 9 a.m. They say yes and sure as heck, they call. Then they tell me to turn on the computer and boot into Windows. I tell them that I don't have Windows. Then they say " are you using Apple" and I say no. That sort of confuses them. Then they tell me that I must have either Windows or Apple. I tell them no, I don't use either one. They ask me what I use. I tell them Linus Ubuntu. That really throws them a curve. I had one guy turn me over to his "supervisor" and he asked me what operating system I was using. I told him Linux Ubuntu version 7.0. He told me he had never heard of it before. I told him he must not be much of a computer guy. Anyway, long story short, I love to mess with those people and waste as much of their time as possible. I could go on and on. There are many great stories to tell. Lately with all the political calls we have been getting, the ones the get past NOMOROBO.com, I always answer "9 1 1, what is your emergency". There will be a pause and they start to hang up. I tell them "don't hang up, we have captured your number and a squad car is being dispatched to your address". They fall all over themselves trying to get out that one.
I love it.!!!
