I need help please... Stop billing me... I need the service canceled.

I have tried to cancel my internet for the pass 4 months. I called on two occasions and I was told that you off line. Unfortunately I cannot afford the subscription because I have a family of three that passes away and I have to take care of two kids. I called to say that telkom needs to give me a reduced rate to pay so the landline can be activated and the internet canceled. So I was told that until I pay the full amount will it only be canceled. Totally unfair as I cannot afford it and I want to cancel the internet so the billing can stop.

Please please assist.
