Multichoice out of line

I had my dstv several times disconnected by someone inside multichoice who knows why and my Dstv is on full package and fully paid up. After numerous calls to the call centre each time my dish was disconnected and staying on the line every time for more than 40 or 50 min on my phone account they could solve the problem and reconnect me just to cut me off a few days later again. I think the people at that call centres are not properly trained fot the jobs they are doing. I dont know what to do anymore and who to phone because every time the same story happens. Hope you can come to my rescue. Thank you
