Endless promises none delivery

In Dec 2015 i called multichoice and i asked they upgrade my subscription from Compact to full view for a month. I was told by the agent i'll have to pay extra R289 in order for this to be done since it was already in the middle of the month. That was done and services were upgraded. In Jan 2016 i realized that we still had full view, i called the callcentre and was advised that i was supposed to have called to cancel after the 30 days even if it was requested on my initial request. I was advised to pay for the arrears and the downgrade was to be done. I have already called almost 2 or 3 twice in Feb and Mar for the very same thing and i kept being told the same story. What is a shock is that all this time i call, no notes are loaded onto the system by the agents i speak to, only the notes of the 24th Feb are recorded. Last week Wednesday, the services were suspended and i called and the very same story repeated, services were reactivated. I was away for Easter, on my return yesterday the services are suspended again. What will take for DSTV to fix this once and for all? The last agent said he'll before 7pm the same day, i'm still waiting for his call and i don't have service?
