Unauthorized debit from bank account

Call center agent contacted me in December 2014, offered me a tablet for R 89 per month on contract. Told me the parcel would be delivered to my address the following week. When confirmation e-mail arrived, additional costs was added for extra features which I didn't ask for. Called to have it removed from my account. later cancelled order. Recently received another call about my order. I said to him I only want the tablet, no other features. He said to me that the amount would be deducted after i received the device. It was not delivered, yet on 2 Feb an amount of more than double the said price, was deducted from my bank account. This for the device I did not receive as well as the extras I specifically said I do not want.<br> <br> Tried to get help from the customer call center to have my money refunded. Operator ends call while I'm talking. Can't get through to them at all, after trying almost 10 times. To me this is non other than *****ing my money. I wish I didn't give them my banking details, it's scary to me and feel I need to warn other customers!
