CANCELLATION OF ADSL

I sent a cancellation request in June of this year for cancelling the account the end of October , I received a call and sms that the account is cancelled and each time I call to get an update they advise that the account is still not cancelled, they will escalate and I phoned again today and still this account is not cancelled. When the lady from Telkom called me she advised that the final account will say final account and it doesn't say that. I want to pay this month account but I know next month I am going to get another one. I have moved out my house and left the devise for the new tenant and now I am worried that the account is still activated on my name. I even got an sms from Telkom that the account is cancelled BUT its not.
