ATMOS Energy Refuses to take my payment, and then turns off my gas & kills my birds and cats Fort Worth Nationwide

I go to pay my bill on line...and all my payments were declined.  I call to make the payment, and again, all my types of payments declined....After talking to a representiitive she told me it was not their fault and to call "Matrtex" who I guess collects payments for them.  I call matrex, was on hold for an hour until someone finally answered and said I was "blocked" from paying.  (Why?). Meanwhile I have someone callining me that they are shutting off my gas.  I explain that I have the money to pay, but your company wont take my money.  I again call ATMOS, expained the sutuation, and they gave me 3 addressses to go to that would take cash.  ALL three places that were listed on the Web sight said thay have nothing to do with ATMOS.  My driving time to each of these places was 2 hours.  I again call ATMOS an they said they alredy turned off my gas.  It is anot 25 degrees.  The next day I went to 3 other places that is listed on rgeit Web sight to pay the bill.  The 3rd on finally was able to pay ATMOS with cash.  Now they refuse to turn on my gas without a large deposit. My cat and 3 parrots  froze to death.  Meanhile, all my credit cards have always been in good standing and have never been declined.
