Incompetence at Homechoice

Homechoice canceled my debit order and I'm not sure why as their customer service doesn't seem to know either. I got a call a month after the cancelation telling me about my unpaid installment and I instructed them to reactivate the debit order immediately as it's a convenient way for me to pay. 3 months later, they still haven't reactivated it and now they tell me that they can't do it since my account is in arrears. Their customer services is not able to resolve this issue. I can't get through to their collections department, keeps saying the network is congested. I Requested a call back as I need to get this resolved and I still have not heard from them, instead I keep getting messages that the account will be handed over due to non payment.
