Who called from 2819543786

Started getting calls from this # a day or two ago.  Haven't answered yet. Caller ID only says Houston, TX.  Never leave message.  How can we rid ourselves of these ***hole scumbags?

calls even though we are on the do not call registry...

keeps calling
when I try to call back, it says number disconnected or no longer in service
numerous calls, numerous

They call all the time on the hour and you answer it and they hang up.

They keep calling here trying to send my husband playboy magazines I have told them twice to stop calling and that he is not getting those nasty magazine.
