This  is absolutely ridiculous, this number (Brothers)  has called here 7 times, once ten minutes apart.  I do not answer!  I have learned
that a system called Teleport can be used to call the states in the USA, they could be in Nigeria, etc., and it appears to be a state side
number.  This 480 is Phoenix, Arizona..  Does anyone  of my fellow posters here know how to shut them down????????  (7 calls just today)
Have been receiving them for about four/five days.  This is really OVER THE TOP......   One person could be correct, perhaps off shore.
