I got a call from this "impossible" number (248-059-4744) an hour and ten minutes ago. I didn't get to it before it stopped ringing. It left no message. My number is on the "do not call list".
It was a recorded message, then I pressed 1 to speak to a person, I asked and he said he said he was with Senior Emergency Care. As I said I was on the do not call list he hung up. I then filed a complaint at https://complaints.donotcall.gov/complaint/complaintcheck.aspx?panel=2
