Just block them....if you have an iphone go to the list of recent callers.....you will see an i to the right of the number....click on that and scroll down.....you will see "block contact"....click on this and they will not be able to call you again....
Got a call from this number saying survey. Answered and no one said anything so I pressed my personal alarm button and let them have a nice blaring noise in their ear.
If any presidential candidate will do anything to get these these scam, robo calls to stop immediately I will vote for them. I don't care if male or female, they will get my #1 vote.
