My experience is that it is some type of a spam call that leaves no message.
They should NOT be call numbers on the no call list. But they are doing it.
Caller ID is "SHS"
Same experience as Ginny above. SHS on Caller ID. Company has called every day for at least 1 week, leaves NO message. Why call continuously but leave no message? Doesn't really matter because I wouldn't return a call from a marketer anyway. And the Do Not Call list is completely worthless because these sham scammers/marketers don't check the list in the first place. Waste of time.
I only answered this call because it has a local area code. When I confirmed that I was the person she asked for she said nothing further and we were disconnected. Caller ID reads SHS.
I answered it one day , and the lady on the other end asked me if i had medicare part a & b I said that I am not old enough for medicare . She said ok and hung up
