BAD SERVICE AND NO CARE ATTITUDE

MY CELLPHONE CONTRACT WAS TRANSFERED TO MTN FROM ALTECH AUTOPAGE. ON THE 23RD MARCH I CALLED THE MTN STORE IN HAZELPARK GERMISTON FOR AN UPGRADE, THE UPGRADE WAS DONE AND SINCE THIS WAS DONE ALL MY INCOMING CALLS SHOW UNKNOWN, I HAVE CALLED MTN AND EMAILED MTN AND HAVE JUST BEEN TOLD NUMEROUS LIES AND TO DATE THE PROBLEM IS STILL NOT FIXED. I HAVE BEEN BACK TO THE STORE AND THEY SAY ITS NOT THEIR PROBLEM IT IS DUE TO THE TRANSFER FROM ALTECH TO MTN. ALSO THEY DO NOT BOTHER TO ANSWER THE PHONE AND THEY HAVE A TERRIBLE CLIENT ATTITUDE, NO CARE ATTITUDE, THEY ALSO DO NOT BOTHER COMING BACK TO A CLIENT.THE TRANSFER WAS COMPLETE ON THE 18TH MARCH SO HOW CAN THIS BE THE PROBLEM. MTN JUST KEEPS SAYING WAIT 2 TO 48 HOURS...IT IS MORE THAN 48 HOURS NOW AND STILL NOTHING....<br>
