Virus scam --pc is not accepting windows updates--do not have a pc

I have been receiving several calls from various numbers.  Today it was 641-555-0149; normally I don't answer however, I figured I would start playing their game.  He told me they were from Smart Tech Computer and they had information that I was having a problem with my computer and wanted to help me fix it.  I laughed and said I don't even own a computer, I do, however I told them I do not and all I have is a Kindle.  He sounded dumfounded and said you don't.  I told him no I don’t and he said, “Oh, I’ll have to get back with you later”.  I hope it's much later.

Lady with Indian accent called.  Said "I am calling from Microsoft about a problem with your computer...OK."  I didn't think or believe that Microsoft would call about something like this, so suspected a scam.  I told her "hold on for sec" while I checked her phone number, and she hung up.  I am on all the do not call lists.  I think these lists don't work for international callers at all, whereas they sometimes help for those originating in the US.

Unwelcome call stating the usual , wanted to talk to me about my computer.  Hung up on the party.

said they were from US Treasury Office & there were tax code violations in my name & I must act now before I am arrested!
