Unauthorized Debit Orders

August 2015 I received a phone call from a consultant at NAAH. The consultant advise that I qualify for up to R 1 500.00 cash back amount. I then asked the consultant to send me all the necessary documentation needed for a debit order to be deducted monthly in order for me to qualify for an amount for up to R 1 500.00. After eight months I haven't received any documentation in order for me to give permission to deduct an uncertain amount from my Bank account monthly. No monthly fees were explained to me during the telephone conversation as I was awaiting the documentation in order for me to read through it and make my decision. I contacted them on 03/05/2016 and asked why they are deducting an amount from my bank account as i did not give them the permission to do so. The consultant advised that the amount is being deducted for accident advice. I then advised that i did not give then permission to deduct any amount from my bank account where after the consultant advised that she will listen to the telephone recording and give me a call back. After she listened to the recording she advised that i did in fact give permission by permitting her to send me the documentation. Therefore according to their policy, i as the client give permission to deduct an uncertain amount from my bank account monthly the moment i ask for documentation to be sent to me. I asked for the recording in order for me to have a listen but was declined the right to listen to the recording. Even if i get a case number at the SAPS,they will still not send me the recording. I then asked to cancel the "agreement" and that they should send me feedback on the cancellation. They phoned me back and said that I have agreed to everything. I again asked for the recordings and they still do not want to send it to me. Not even with a police case number. Please give me advise in what to do with this.
