ILLITERATE SERVICE AND CLIENT CARE

I HAVE HAD MY CONTRACT WITH VODACOM FOR OVER 4 YEARS NOW AND I HAVE BEEN CONTACTING VODACOM SINCE JULY WITH REGARDS TO MY UPGRADE. THE 1ST PERSON SAID THAT I CAN COME TO FOR THE UPGRADE FROM THE 1ST OF OCTOBER THEN THE NEXT PERSON SAID THAT I SHOULD COME 7 DAYS BEFORE THE 28TH AND THE ANOTHER PERSON SAID I MUST JUST COME AFTER THE 28TH. I FIRST WENT TO CRESTA AND THE SAID THAT I CAN UPGRADE AND EVERYTHING IN OKAY BUT THEY DONT HAVE STOCK OF THE PHONE AND THEN I WENT TO HYDE PARK AND THEY DO HAVE STOCK BUT BECAUSE OF SOME ERROR OVER 3 MONTHS AGO I SHOULD COME AFTER THE 1ST OF NOVEMBER, I CONTACTED THEM TODAY AND NOW HAVE BEEN INFORMED THAT I DONT QUALIFY FOR AN UPGRADE EVEN THOUGH I AM PAYING EACH AND EVERY MONTH. THIS IS THE WORST CLIENT SERVICE I HAVE EVER RECEIVED AND WONT REFER VODACOM TO ANYONE. IF THEY CAN DO THIS TO ME AFTER BEING WITH THEM FOR YEARS IMAGINE WHAT THEY CAN DO TO YOU. THEY HAVE VIOLATED MY CONSUMER ACT AND I AM APPALLED
