Back to back calling!  It is ridiculous!

Do a search on call blocking devices and phones.If its a cell phone, there are free call blocking apps out there including trac & straight talk.

I've had 5 calls from this number that is disconnected in 30 minutes and there is never anyone on the line. This pisses me off and disrupts my day. I'd like to catch this [***] and kick his nuts up to his throat!

Another Microsoft your computer is in infected scam

They claim to be Windows and that there is problems with your computer.  I never heard a guy named Mike with such a STRONG accent :)   He was rude and hung up once I told him there is nothing wrong with the computer and take me off the calling list
