Vodacom debiting closed account

In September I was contacted by the Vodacom ***** department where I was informed that they suspect ***** being committed on my account, I advised the person that this must be true because I weren't near Richards Bay as I am staying in Alberton Gauteng. The person advised me that they will arrest that person immediately and the upgrade will be reversed. I Sent Vodacom all the needed information they wanted and almost 5 moths later I am still being debited. The last month I was debited by R7937.99 and before that by R 2468.97 after the account was supposedly cancelled. A total of R10 406.96. And that for a R200.00 pm contract. I spoke to the Richards Bay branch and they confirmed that they ended the contract and will reimburse me and are still waiting for that as well. It might not sound like a lot of money but you won't expect this type of service from a huge company like Vodacom.
