Cancellation + Billing

I wrote a complaint stating i couldnt get through to cancel my ADSL. i received a call and was told that my Internet has been cancelled. i received an SMS. I did request a proof of cancellation. However now when logging on to my telkom acoount i see that i have an outstanding balance. The same balance amount for which payment was made at the beginning of September. I logged this as a dispute but no contact has been made. I also dont know whether my adsl has been cancelled or not as I received cancellation forms. I'm not sure if this was received because of previous requests or if it still relates to the same query. i need someone to contact me urgently
