Who called from 7204526362

this number calls me every once and a while, they never leave a message.  I call back and tell them to not call my number and they guy keeps saying I can't hear you call back again.  Even though he can hear me cause he waits until I'm done talking to say that he can't hear me.

I am on the do not call list----HELLO.  WHY are we still getting calls????

Call them back and keep calling, its a scam telemarketer.

recorded message left on my voice mail by this number:
"Are you an experienced truck driver?........"

Called my wireless number.  Didn't recognize it, so I didn't answer.  It/they left no message.
