Phone not working and still being debited

<p>I got a new vodacom contract from chatz vodacom mall of Africa. the phone has never worked. I called vodacom multiple times. they could not help. I took it back to store and they could not help. The phone is still there.</p> <p> </p> <p>i have requested that i want to cancel the contract and i was told that they cant really help because they cant sell my phone now that it has being used. they continue debiting my account and i dont have the phone with me.</p> <p> </p> <p>this is so *******. where does one complain so i get the debit orders to stop and refunded for the previous ones. </p>
