I got a call from this number and he said something about my computer.  I told him in no uncertain terms he did not even know if I had a computer or not.  I told him I was on the Do Not Call list and if they called again I was calling and reporting them to the law and Do Not Call.  Did not get to finish because he hung up on me.  So very much more I wanted to say.  lol  I normally do not answer from numbers I don't know but I did this time.  It won't happen again because it will go to voice mail.  Sick and tired of these scammers.
