Awaiting 4 weeks for my Vodacom Refund

Good Day... About a month ago i complained about Vodacom not cancelling my Wifi contract as instructed... After my complaint I received a call from Vodacom and the Contract was cancelled... I was told by the Consultant that 2 months money needed to be refunded to me, and that it would take upto 7days to reflect in my account.. Its now 4 weeks later & still nothing. Its becomming really frustrating, as the money was taken and my account went into overdraft and i had to borrow money to sort tye overdtaft out. If my money is not given back to me within the next 7 days, i will take legal action & claim for damages & the inconvenience Vodacom has put me through...
