UPGRADE LIMIT NOT INCREASED FOR PASSED 3 MONTHS

I CONTACTED MTN TO UPGRADE MY PHONE SINCE THE 02/01/2015 AFTER NUMEROUS CALLS I WAS THEN ADVISED THAT THE DEPARTMENT THAT INCRESES LIMITS DOES NOT HAVE A CONTACT NUMBER AND THEY ARE DELAYING THE PROCESS, I SHOULD TRY A BRANCH, I THEN VISITED THE GLEM MTN BRANCH AND THEY DID THE UPGRADE FOR ME, A WEEK LATER MY SERVICE WAS SUPPENDED, I THEN CALLED MTN AND THEY ADVISED THE UPGRADE LIMIT WAS NOT DONE, I THEN WENT BACK TO THE BRANCH WHO ADVISED ME THAT THEY WILL UNBLOCK THE PHONE, FEBRUARY THE SAME THING HAPPENED, YESTERDAY 05/03/2015 THE PHONE WAS SUSPENDED ONCE AGAIN, AN AGENT INFORMED ME THAT I MUST CALL BACK AGAIN AND ADVISE THEM THAT THE LIMIT INCREASE WAS NOT DONE,<br> I HAVE BEEN CALLING MTN FROM MY LAND LINE ON *** AND EVERYTIME A CONSULTANT ANSWERS IT SOUNDS LIKE THEY ARE DROPPING THE CALLS ON ME, THIS IS REALY FRUSTRATING NOW, I AM A GOOD CLIENT AND MAKE SURE THAT MY PREMIUMS ARE ALWAYS PAID ON TIME, ALL I WANT IS FOR THE INCREASE LIMITS TO BE COMPLETED SO THAT MY LINE DOES NOT GET SUSPENDED ALL THE TIME, I CANNOT CARRY ON LIKE THIS FOR THE NEXT 22 MONTHS OF MY CONTRACT, IF THERE IS ANYONE AT MTN WHO STILL CARES, PLEASE ASSIST ME. <br> <br> YOURS FAITHFULLY<br> AN UPSET CLIENT
