Vodacom false adverti*****t, lies, no feedback

Vodacom has proven to be the most ************* supplier that ive ever come across. During September 2014, Vodacom offered me a notebook on a uncapped data package. Soon after receiving the product, I learnt that the adverti*****t was false as the data only last for a day. When I complained to Vodacom within the cancellation period, they acknowledged the mistake made on their side and agreed to accept the notebook and cancel the 24 month contract. A few week ago, I discovered, that Vodacom has been debiting my bank account for the notebook on a monthly basis since September 2014. This is not the biggest problem I have. When I called Vodacom call centre/vodacomdirect/Vodacom client service/vodacomcancellations department to enquire about this, they ensured me that the mistake will be rectified and monies will be refunded. After back and forth conversations over a period of 3 weeks, I received no feedback on the matter and once again, my bank account was debited for something that was supposed to have cancelled. I do not enjoy spending most of my time, being placed on hold or listening to voicerecordings. This matter is becoming a legal issue to me, as Vodacom is very quick
