DSTV WON'T ACKNOWLEDGE PAYMENT

HOW IS IT THAT AFTER PAYING MY MONTHLY SUBS YEAR AFTER YEAR, SUDDENLY DSTV CLAIMS I HAVEN'T PAID. I HAVE. I HAVE SENT THROUGH THE POP AND ALL I GET IS AN AUTOMATED RESPONSE. I CALL AND ALL THEY IS SEND THROUGH THE POP, I DO. THE MONEY HAS LEFT MY ACCOUNT AND THEY CLAIM THEY HAVEN'T RECEIVED IT. ITS BEEN OVER A WEEK AND WHAT CAN I DO? STANDARD BANK HAS CONFIRMED THE MONEY WAS PAID INTO THEIR ACCOUNT - THE SAME ACCOUNT AS ALL THE PREVIOUS MONTHS, THE SAME PAYMENT REFERENCE. CLEARLY DSTV HAS NOT ALLOCATED MY PAYMENT CORRECTLY AND ARE MAKING NO EFFORT TO DO IT. IN THE MEANTIME THEY CUT ME OFF. AND I WAIT. NO DSTV.
