Overcharged - waiting 3 months for refund

I overpaid vodacom after cancelling my contract which means that there is a positive amount of R300 in my vodacom account. I want that money in my bank account. On the 13th October I went into a vodacom store to sort out the matter, they put me on the phone and I was told to fax proof of account and the money would be in my account in 3 weeks (3 November) which did not happen. On 5 December I went back in - waited the usual hour to be helped and the person who helped me discovered that the call centre now requested a proof of payment (nobody told me - I had to go find out) and they said that they cannot help - I have to phone in myself. I phoned in and was told that I need to email proof of payment to a cell number :-) which did not work obviously so after calling in again I sent proof of payment in the form of a bank statement to ********** Today on 10 December I sent an additional proof of payment from the bank. I have not received any response from vodacom. All i want is the money that rightfully belongs to me.

If the matter is not settled by the end of this Month I will be forced to resort to the small claims court which is unnecessary and would end up costing vodacom more money and at the very least negatively impact the company's reputation. Please not that this is not a threat - it's me politely informing vodacom of the action (and using my constitutional right) that will be taken given that more than enough time has passed for this matter to be resolved taking into account that I am the one going into vodacom stores, phoning and emailing without getting responses from vodacom. Contact me via email.
