This number keeps calling saying something about a problem with my windows computer. I tell them to shove it but they keep calling.

just tell them you have an Apple computer

I have received many calls from this number.  Most of the time I wouldn't answer because I was busy or didn't feel like dealing with it because I new by the sketchy number it was spam.  I answered once though - when I said "hello," as always, there was a silence.  Instead of someone saying hello back, a machine said "goodbye" and hung up.  Normally if it's a telemarketer, I tell them that I registered all my numbers with the do-not-call registry and I can sue them for calling and to take me off their calling list as a warning.  Since this didn't even give me the chance to do that, I'm hoping something like this report will help stop them from not just calling me but others.

Called every day for three days already

They just called me for the third time.  The first 2 times in a week they called I did not answer. They failed to leave a message but I could here a second or 2 of someone talking.
This time I answered & a man id'd himself some strange name (heavy Indian accent) & said my MS operating system has been sending him error codes so he would like to help me fix that.  I decided to have fun with him so I said "do you need my CC number?".
He said no. Then he asked me to turn on my PC & so I replied..."hold on...my brother is right here & he works for Microsoft in the internet security division & we are connecting a trace on this call so hold on a second please".
Boom....the scammer hung up.
End of call.
