unfair billing and services provider

I'm a customer ,I make use of the premium package which package which is R699 per month and R50 reconnection fees. I pay my account manually every month.<br> I don't make use of a debit order because I dont always make use of dstv as for im working away from home.<br> Starting april 1 I didnt make payment, because i was working away and didnt require the service. On the 30th of April I wanted to reconnect my account, and was informed that the amount outstanding to be paid to reconnect is R1120, when I phoned the customer care line I was informed that the additional costs was due to the fact that my Dstv service was only disconnected on the 16th of April and they stated that it was my responsibility to inform them of my intention not to make use of the service or for them to reconnect my service. When I asked the supervisor at their customer care helpline how I was supposed into be aware of that. She told me that this was stated in their Terms and conditions. I was sitting with the terms and conditions in front of me and asked her where I could find it. She wasn't able to assist me.I think its unfair to be billed for a service not requested or require.
