caller i.d. Said Dunn N C and when not answered, left no message on answer machine.  I called the number and it cannot be completed as dialed.  We are also on the Do NoT CALL list.  Doesn't seem to matter.

Caller hung up without leaving a message when call was answered by machine.

Called two times in a row never answered and they did not leave a message

Medical alert scam!

They call and keep asking for my deceased  husband.
