Keep getting calls from person who says we have a medical alert system
that is already paid for-just need to set up an appointment to install.  I
did speak with someone at one point during one of these calls and ask
them to take our number off their calling list.  The calls stopped for about
two weeks and then started again today-this time it is a woman instead of
a man-these are robo calls

When does "do not call" registry come into play here?  When will someone do something about our privacy?

I got a call from this number at 5 pm just after I walked in from a long day at work. Big mistake on the caller's part.  I don't answer calls from unknown numbers but I had had it with this number constantly showing up.  Whoever this person was starts out with, "I'm calling from the shipping department of your medical alert company."  Before he could say another word, I ripped into him with "we don't HAVE a medical alert company and take us off your GD list.  As I was hanging up, I heard him say, "but...."  But nothin' pal, call me back again and you'll get the same response.

Calls have come in from this number several times in one week.  When I return call, says "Number can not be completed as dialed".  So how do I get on DNC list if I can't reach the caller?

I got two phone calls from this number today. Both times I let it go to voicemail. Just as posted above, they claim someone has already paid for the medical alert system... etc.The robomessage never identifies the company whom they represent. It just says "just like on TV!. You've fallen you can't get up!"
And when I tried calling back the number, it says "call cannot be completed as dialed". TOTAL SCAM!
