PATHETIC -NO COMMUNICATION-DISAPPOINTING SERVICE

I DID AN UPGRADE A WEEK AGO WITH GRANNY AT THE CALL CENTRE. SHE TOOK DOWN ALL THE INFO REQUIRED AND ADVISED THAT I SHOULD RECEIVE MY PHONE WITHIN THE WEEK. I CALLED YESTERDAY TO FIND OUT THE WHEREABOUTS OF THE PHONE ONLY TO BE ADVISED THAT IT COULD NOT BE DELIVERED DUE TO CREDIT LIMIT INCREASE. WHERE IS THE COMMUNICATION IN ALL OF THIS. SHE DID NOT EVEN CALL TO ADVISE THAT. THE CONSULTANT I SPOKE TO YESTERDAY SAID GRANNY SHOULD OF ADVISED ME AND SHE WILL GET HER TO CALL ME IMMEDIATELY. STILL NO CALL OR CONTACT FROM MTN. I HAVE 3 CONTRACTS. 2 WITH CELL C AND I PAY FAR HIGHER RATES THAN WHAT IM PAYING MTN. I HAVE BEEN A LOYAL PAYING CUSTOMER FOR YEARS AND THIS IS PATHETIC SERVICE. NO WONDER MORE PEOPLE ARE LEAVING MTN AND GOING TO CELL C. I WOULD LIKE TO CANCEL MY CONTRACT WITH MTN COMPLETELY. I HAVE 2 S5'S-1 MICROSOFT LUMIA 930 THAT I PAID R6700 CASH LAST WEEK FOR SO WHAT IS THE PROBLEM. I HAVE NEVER MISSED A PAYMENT ONCE WITH MTN EVER. CONTACT ME IMMEDIATELY AND ADVISE ME THE OUTCOME SO I CAN GET THE DARN PHONE THAT I REQUESTED FROM SOMEWHERE ELSE
