Unable to Terminate Account

I app**** on the 24 Aug 2015 to terminate a data bundle account as I was not using it hoping to save some money. The expiry date is July 2016 so when I enquired on the 24 Aug 2015 they told me that it would take 20 working days to finalise - in writing by the way. After about 30 different calls and about 50 e mails, different people each up to and including 24 Nov 2015 I FINALLY managed to get an Early Termination figure from Mpho Junitha Papole. I held on for about 50 minutes between her and a Mr Abdussamad Mohamed who finally gave me the finally figure or R124.00, I asked for it in writing. She said that I needed to use the remaining data before the 11th Dec 2015, and to call on the 11th Dec to confirm that the account was terminated. I rushed immediately to the MTN store at Eastgate, paid over the R124.00, got a receipt and believed I was finally rid of MTN. I called on the 11th December to confirm that the account was closed, and my worst nightmare, all over again.....the account was open and in arrears, I had to pay R52.00 to bring the account up to date before I could get a new Early Termination figure...WHATEVER YOU DO, DO NOT OPEN AN ACCOUNT WITH MTN. VODACOM GOOD.
