Why is Telkom not canceled, utterly bad service

Tell me why Telkom is not canceled. My contract with them ended in August but somehow they still deducting from my account. Was in contact with them to make sure that it was indeed closed and was confirmed it was. I went to their store, emails and calls so to avoid this from happening but here we are with this ridiculous network.Tell me why I'm waking up to their debit order.
