Who called from 4023224043

Wanted to help me with getting education I think . I told them I was not interested and to put me on the do not call list. That was on 4/6/15 .

Called about "my doctor" who reported that I am dealing with pain management.....  They said they were told by my doctor to call me.  When I asked from where, they hung up on me.

Just called around noon, when i picked up there was no response

Got a call, I did not recognize the number and let it go into my voice mail.  "It" left no message.
