Calls my number and hangs up upon my answering.  Very annoying as we are elderly and it is a chore
to get to the phone.  Perhaps they are in contact with local burglars who want to know if anyone is home so they can
rob our home. We have signed up for the do not call list numerous times; what a joke that is since the calls
since signing up for it have increased.

Calls then hangs up and calls back in a few minutes.

Just called and told me that there are cyber attacks on my Windows program on my computer. I do not have Windows.

Scammers don't care. Their little scamming brains are wired to believe EVERYONE has Windows. Next time try talking about the windows in your house to REALLY throw them for a loop and get them off-script (they REALLY hate that!)
