Unfair treatment to Multichoice users

I have a major concern, I am paying for my parents package for a ling time, I am on the full package, approx R1100 per month, I believe that users who are on the compact package are getting the full package for a period of time, they are not paying for this, This is a major shortcoming from multichoice and it seems at though a good history is doing my parents in! I need feedback regarding this unfair treatment.
