Who called from 8573175345

Left several calls; no message. Called ID: Out of Area.

Calls at least once a week.  Called 4 times yesterday (I did not pick up).  Never leaves a voice message.

called me. VM is for 3 sec.. says nothing.

It's a third party for Comcast. You can add you name to the do not call list if you call back.

Exactly what does that mean John???  If you called back and just got a recorded message, how would that prove that it was a call "for Comcast".  Please add some real and meaningful details.  Thanks!
