Terrible customer service!

I have a pricelock package which was agreed to be R550 for extra view. I have never paid that amount in the 7 months I’ve had it. Every month the amount changes and is always MORE than what was agreed on. As we speak, my subscription has been suspended for a week. Mind you, my debit order date is for the last day of the month and when I call them on a number I was given by an agent from Multichoice, I hold for an hour at a time with no assistance. They never answer the phone and when I call DSTV, they tell me I should call Pricelock. What am I suppose to do now?! Why offer a product which can’t be managed or managed so poorly. I don’t know what to do now!
