There is an article in the July- August issue of the AARP Bulletin that warns of, and explains, the medic alert for seniors scam, that is well worth the reading.
This number calls me every couple of days. Never leaves a message. Thanks to posts, I know the intent of the call so will continue to not answer. l 347 200 3682
Look up your Attorney General website and see if it has online complaint forms for unwanted calls of any kind. I don't get these calls very often anymore since I've been reporting them to the Attorney General especially since I'm on the "National Do Not Call Registry". As strange as it sounds, I've been able to stop some of these calls by calling that number back where you can request to be put on the "Do Not Call" list and it works. However, the telemarketer will just ignore you and hang up if you just try to tell them. This has stopped robocalls and scammers using that system.
