Who called from 6786060057

this is some kinda religious number i get a call at least 5 times a week.

Yes I have been receiving this call too

That person call at least  twice a week

They call from 407-542-9787 and leave the number 678-606-0057 to call back but never say who they are, or who they are looking for in the message

Get 4 to 5 calls a week from different numbers each time.  I block ALL calls.  He says what his name is but you cannot understand it.  Any ideas how notify somebody about this idiot and assistant?  Very annoying!!  Last two numbers are:201-492-9181 Jersey City, NJ and 505-359-6558 Albuquerque, NM.  They give a number to call back.678-606-0057
