Cancellation denied and theft through debit order

I requested via email (i have evidence) that upon expiry of my contract, it be cancelled, two months prior to expiry.<br> <br> Three months after the expiry date of the contract, i discover that my contract was not cancelled. In fact it was continued and the debit order had *******ly taken money out of my account.<br> <br> I rushed into the nearest virgin mobile store (East-gate) and explained the situation, showed the supervisor there that i had in fact requested cancellation, and asked him to ensure it was cancelled and my money paid back.<br> <br> Two months later, the contract has still not been cancelled, the debit order continues to go off (my bank say they are not authorised to stop it!?) and i have not received a single phone call or email to follow up and deal with the situation despite having sent numerous emails and having made many phone calls.<br> <br> This is straight up theft.
