Ripped of by Multichoice

To say I'm disappointed is one thing, the experience that multi choice is now portraying is very sad. My mom opted for an Explora. Ok everything was fine she was told her monthly subscription will R628. Ok she accept and even opted for a debit order. Last year she got an sms telling her R898 will be deducted on her account end of the month. Only to find that there was Netflix that was opened that she was not even aware of. She canceled it. But few months later she is getting sms of 898 that she must pay. Why is multichoice ripping of people this at a time like this???? This is so disappointing
