Delay in canceling packages on old decoder

I’ve been trying to cancel the dstv packages linked to my old decoder (DSD1131) for the last month:

1) I tried via self service on the website and the site hung 2) I tried via the iOS dstv app and the app hung 3) I called the call centre and spoke to Katlego and was assured that the packages would be disconnected of my old decoder. ***-I57

Come October, and I see the packages On the old decoder are still active and I have an outstanding bill of R 634.

Please resolve ASAP: - cancel packages of old decoder - clear incorrect outstanding amount

I should only be paying R 385 p/m for my Indian subscription package.
