Who called from 6104927337

Got this unwanted call on my cell phone during work today.  Did not answer it and I am on the
DO NOT CALL List.

Got this call on my cell this afternoon.  Did not answer and no message was left.

WCA Subscriber Services? Computerized call.

Got this call too today at work twice.  First time I didn't answer it.  The second time I did and was hung up on.

Got a call from this number at work looking for someone who left.  Clearly non-American man said his name was Justin White, that he was 25, asked if I was married.  I think it was a collection agency for the woman who left.  Totally creepy.  Would like to call police.
