Bad service and billing issues

I have been having the worst experience Telkom for the past 3 months now. The call centre agents don't listen and make false promises. My bank account is being billing religiously every month but apparently, I am still in arrears with an amount from July! Ridiculous! For some reason nobody understands when I call and ask what is happening. I requested a call back from the Manager, no one has called me. I just want my account fixed.
