Still waiting for technical department to resolve

I have phone Multi Choice call centre times without numbers but still I am waiting for assistance. I have been getting the same error message every night the same time.\ Waiting for connection from primary decoder". This unfortunately is resolved sometimes this next morning but low and behold come evening when I want to enjoy my TV in the privacy of my room the same happens. I have called Multi Choice many time and requested I be contacted after 5 in the evening. The following day while at work I get a call from them. I would refer the agent to there notes and he/she would read back exactly what time I requested to be contacted. Apologising profusely but no one would phone and history repeat it self every time I phone. And here I find myself laying in bed wanting to watch TV and the same error message. This is so flipped frustrating. I pay my almost R800 religiously so why am I being subjected to this nonsense. This is my last hope."""
