Who called from 8647218007

Rang cell phone once.  I did not answer. No message left.

Rang once and then they hung up. Number blocked.

same as others. one ring, hangs up. no message. similar call the other day, may have been another number. dialed back, recording about visiting website, qualified for "reward".  no thanks.

Angel, I also am on the do not call list. Why I don't know. What good does it do? Doesn't do any good at all.

The door not call list seems to be a lost cause
