WORSE SERVICE EVER!!!

i AM VERY DISAPPOINTED WITH THE SERVICE I RECEIVED FROM VODACOM CENTURION MALL NEAR CHECKERS , I WENT THERE ON THE 25TH OF JUNE TO TAKE A NEW CONTRACT SINCE MY PHONE WAS GIVING ME PROBLEMS. THEY TOLD ME THE PRO- RATA WILL BE DEBITED WITHIN 24 OR 48 HOURS .I WAS SURPRISED WHEN NOTHING WAS BEING DEBITED. THEN I STARTED RECEIVING VOICE MESSAGE THAT MY ACCOUNT IS IN ARREARS. I DECIDED TO VISIT THE VODASHOP WHERE I TOOK THE CONTRACT TO CHECK WHATS GOING ON.THEY TOLD ME VODACOM TRIED TO DEBIT AND THERE WAS INSUFFICIENT FUNDS I SURPRISED AND TOLD THEM THAT IT IS IMPOSSIBLE. I ASKED THEM TO CHECK WHAT AMOUNT DID THEY TRY TO DEBIT.T THEY COULD'T EVEN OPERATE THEIR SYSTEMS THEY COULD NOT EVEN TELL ME HOW MUCH WAS SUPPOSE TO BE DEBITED.THEN I SAW ON THE SYSTEM AN AMOUNT OF R10 000 I KEPT ASKING THEM WHAT IS THAT R10 000 CASH FOR ,THEY COULD NOT ANSWER.WHEN I CALLED THE CALL CENTRE LATER I WAS TOLD THAT THE PERSON THAT WAS HELPING ME AT VODACOM CENTURION HER NAME IS THULI,SHE MADE AN INVOICE THAT I WAS PAYING OFF MY PREVIOUS CONTRACT. I NEVER IN OUR CONVERSATION SAID ANYTHING ABOUT PAYING OFF MY CONTRACT, SO MY ACCOUNT SHOWS IN ARREARS OF R 10000 THAT IS WHY THEY COULD NOT DEBIT. VODACOM MUST FIX THIS, ON MY PAY DAY I DON'T WANT TO BE DEBITED THAT R 11 000 FOR SOMETHING WE DID NOT AGREE ON AND I HOPE THIS WILL NOT REFLECT BADLY ON MY CREDIT RECORD. I HAVE BEEN WITH VODACOM FOR OVER 5 YEARS BUT IF I WILL KEEP GETTING THIS POOR SERVICE I WILL TAKE MY CONTRACT SOMEWHERE ELSE. I AM VERY DISAPPOINTED OF SUCH PROFESSIONALISM, WORSE THEY GIVE YOU A VOUCHER BUT THERE'S NO ITEM IN STORE
