CELL SUSPENDED

MY COMPLAIN IS THAT I KEEP ON PHONING AUTOPAGE GOING INTO THEIR OFFICES AND THEY KEEP ON TELLING ME THEIR IS NOTHING WRONG WITH MY PHONE LINE BUT THE MORE I TELL THEM IM SUSPENDED THEY LOOK INTO ACCOUNT AND ALL IN ORDER. DEBIT ORDER WAS REVERSED LAST MONTH BUT PAID BY EFT AND NEW DEBIT ORDER HAS BEEN PUT IN PLACE. SO ACCOUNT IS NOT BEHIND AND THEY HAVE AGREED ON THIS. SO WHAT IS THE PROBLEM HOW COME I STILL CANT RECEIVE CALL OR MAKE CALLS.
