Why pay for a service that I am not getting?

My decoder switch off on 19 January 2019, I took it to Midrand - Decp Centre Dstv outlet. I arrived there around 11am and was promised that it will take 5 hours to connect my service. To my surprised when i arrived at the store around 4pm I was still not connected until the following day. The whole of saturday i was not connected. What was annoying is that i had to do the calling and follow up while promised that they will call me back. Four days later I still cannot access certain channels. Yesterday when i called the call centre agent said it will take 24 hours to reconnect channel 307. But we are still not connected. Why am I paying for a service that is not satisfactory? When it comes to your payments you sent smses 6 days prior to due date and you are quick to disconnect with an additional charge. I am not happy with the service i have received in this month. Paying for a service which does not connect to all channels i am paying for
