Who called from 8489634853

I have received several call from this number and when I answer no one is there......I am on the do not call list and do not wish to be disturbed at home.............I would like this to stop

calls often, also on DO NO CALL LIST , they let the phone ring 2x  and sometimes 3x, never leave message. Name unavailable on caller ID.

On DNC list also.  Apparently this list does NOT work anymore.  This call was identified as Dom Repub call. I am NOT dealing w/ anyone overseas. NO message left.  Yes rings 3x and then stops.
