Dstv price lock is a ****

Dstv price lock is a **** every month my bill is always high not accurate then they cut off the service without even notifying you or even fixing the error , was told that I will be paying R549 however in recent months I was made to pay over the amount I signed up for .Yes I agree that that I have showmax add on but I never requested for the disney app which now it has been charged on my subscription which is uncalled for .am sick and tired with multichoice over charging me for this whole 3 years and not taking accountability for ripping me off am going to the consumer tribunal to seek fairness cause really I can't taken for ride like this .
