medical alter systems association keep on call on my mobile even if they've been told several times to stop it!!

the scammers are selling medical alert systems to the senior citizens. luckily i was visiting my parents and answered this call. maybe they had bought it.

The name on caller ID said "alert".  I am so beleaguered with telescammers I started to keep a diary of the calls.  I had a call that said "alert" in November from two different numbers (213-710-3617 and 213-710-8660).  They were offering seniors $3,000 dollars worth of free grocery coupons and a free medic alert bracelet.  Since these callers spoof their numbers to keep from being found, I wouldn't be surprised if this is the same outfit. Of course they never left a message about what they were SELLING.   By the way, over 3 months I logged over 100 unique phone numbers and much of them were the exact same people.  I have discovered that if I don't answer callers who don't identify themselves or have suspicious names, no matter how mad they make me, they will eventually slack off.  

Caller ID said ACS V EXPANS  
THE WEBSITES SAID EXPAND YOUR PHONE SERVICE TO 14 LINES OR MORE OPTIONS.

Caller ID said ALERT. No message left. I think this may be the first time for this number, but not certain. I have had no recent calls from the medic alert scammers with their $3000 grocery coupons, so I hope it is not starting up again. Have never answered a single one of the calls, from a dozen different numbers all pushing the same agenda.
