Someone from this # (972-253-6401) called me yesterday and didn't leave a message, and today someone called me from 972-253-3401 and didn't leave a message either.  Since the #'s are so similar, I thought that maybe they are related somehow.  Does anyone know?

I received a call from 972-253-6401.  I answered, but no one responded.  This isn't the first time it has happened with this number.  Anyone with any informaiton?

A search indicates a land line number in Irving, TX.  After some googling, I believe it is a company asking for money.  Similar numbers from the area 972-253-3401 and 972-253-6600.  Some say it's a fundraising organization.

I OFTEN GET CALLS SOMETIMES AFTER 9 P.M. THEY ALWAYS HANG UP OR NEVER LEAVE A MESSAGE. CALLER ID SAYS ANAVAILABLE.
