*********** that I cannot comprehend

I sent a request on 4 October to have my Telkom residential service canceled. I was emailed a reference number and acknowledgment from Telkom that they have received the request. I decided to call their call centre towards the end of October just to confirm that my request has been received and it is all in order. The agent who took my call stated that it will be cancelled effective 4 November because it is a months notice and that I would receive confirmation of this as well. I understood that it is a months notice and agreed to wait till the 4 November. Today is the 16 November and as I suspected, I received a bill from Telkom dated 12 November requesting me to make payment by 5 December.

Can somebody please tell me how do you get rid of such a pathetic company in an easier way. I do not wish to deal with them and their inefficiencies anymore.
