Who called from 3606339031

Or just actually enforce the ones we have already!

I received a call from this number on my cell.  Did not answer since I didn't recognize it and no message was left.

I get at least 3 or 4 calls a week from this number and it is always on my cell.  I have never answered yet it must be a scam.

who is this...

Received a call just now and I didn't answer it because the number was unknown to me.  No message left.  This is not the first time this number has called me and not left a message.  I am on the do not call registry as well.
