Cancellation of contract- Didn't happen, still being charged 7 months later

<p>I called the call centre on 12/2/2016 reference nr ********** 51 requesting to cancel my contract and make it prepaid. I now see that every month since then the debit order for the contract has been coming off my bank account. From March to September R1085... I called the call centre this morning, reference nr ********** 75 to find out why it had not been cancelled and why I have been charged for a contract 1 I cancelled and 2 I haven't used since I thought I cancelled it in February. The lady told me that the email was never sent to the retentions dept to cancel my contract. This is just ridiculous and extremely bad service. I want to know how I go about actually cancelling this contract and getting my refund for being charged for 7 months. </p>
