The worst billing system ever

Judging by the complaints on this website, Multichoice has the worst billing system on the planet. Every time i make a change, they get the billing wrong. And i don't blame the call centre, i blame the system.<br> In my latest case, i made a simple change whereby i swopped my 2 decoders primary and secondary status (purely because these decoders are so reliable, that when the primary fails, the secondary wont work).<br> This was in April. I was then Charged R479 instead on R399, which meant they doubled charged me for extraview (R80). Its as simple as that yet 3 calls to their agents, and it has not been resolved.<br>
