VERY POOR CUSTOMER SERVICE AND KNOWLEDGE OF THEIR BUSINESS!!!!

I HAVE HAD MY CONTRACT FOR APPROXIMATELY 30 YEARS AND PAYMENT WAS MADE BY DEBIT ORDER EVERY MONTH. SUDDENLY AT THE END OF APRIL I COULD NOT USE MY PHONE AS THE CONTRACT HAD BEEN CANCELLED WITHOUT MY KNOWLEDGE. SINCE THEN I HAVE TRIED UNSUCCESSFULLY TO FIND OUT WHY THIS CONTRACT WAS CANCELLED. I SPENT ABOUT 3 HOURS AT THE FOURWAYS MALL STORE AND ANOTHER 5 HOURS AT THE HEAD OFFICE IN 14TH AVENUE, ROODEPOORT. THAT IS APART FROM THE HUNDREDS OF PEOPLE I HAVE SPOKEN TO TELEPHONICALLY AT MTN. I THINK THAT I WAS PUT THROUGH EVERY DEPARTMENT AT MTN. UP TO NOW NOBODY IN THAT LARGE ORGANISATION CAN TELL ME WHAT HAPPENED TO MY CONTRACTS. UNFORTUNATELY I HAD ANOTHER 2 CONTRACTS LINKED TO MY ACCOUNT WHICH WERE ALSO DISCONNECTED. WHAT IS EVEN WORSE IS THAT I WAS TOLD I COULD LOSE THESE CELLPHONE NUMBERS WHICH I HAVE HAD FOR A LONG LONG TIME.
