MultiChoice *****sters

For the past 2 months everytime I want to pay my MultiChoice account, my amount due is way more than I normally pay. I have found out that they upgrade my package to family without my consent and when I enquire about it they tell me that I will remain disconnected until I pay the amount of R270 for a package I haven't upgrade but they did for the 2nd consecutive month. I normally pay R130 and the live chat agents are so useless they can't provide me with any information
