After missing their calls, I called back to see who it was.  I didn't get a live person, instead I got a recording to press 1 to be added to the do not call request list.  I did that Monday and I think it worked as so far I haven't gotten any more calls.

got a call from this 231-794-2568 early morning saying that I have received a free I can't get up system and 3000.00 free groceries  and to press #1 for the shipping.  No one answered.  This was a Alert system
