Shocking service and paying premium for something that I don't get

Have been a loyal client for over 20 years and cannot believe the **** service from the call centre. Have been struggling with my 3 decoders for a while and everytime there is a different excuse. Today the last straw... been told my installation done by DSTV accredited installer-what a joke- is wrong. It's been working all along and then the agent when asked what all of a sudden its not working, tells me if I think its right then I must take all decoders to multichoice and see whatbthey say. I asked a perfectly straight forward question. So now again I am paying for something I don't get and the error is that I have been suspended ... when asked why I was told I'm not suspended. SHOCKING
