Subcription Mess - DSTV App

I changed my subscription on the app on Saturday, since them, I have been receiving errors on the subscription and no one has assisted me on your call centre, I keep getting put on hold with no assistance. I have been calling your call centre for 3 days now none stop. No-one bothers to fix the problem and assist. The app is now asking me to pay more money, this is getting frustrating. I paid more money than I should now on a compact subscription. This is not what I pay for with DSTV. The decoder is still not working and I still don't have assistance from your team.
