Multichoice is busy shortchanging subscribers with their annual subscription

I initialized an annual account where I pay a lumpsum for 11 months and get the 12th month free on 1 June 2017. However, in March 2018, 3 months before June 2018 comes, I am getting SMSes where Multichoice is requiring that I make payment for another annual subscription where I will get the 12th month free.

It is clear that for the annual subscription, I pay for 9 months and get ZERO months free. In short I am being **********. Please fix this. I should only get a notification to pay just before 1 June 2018. Not 3 months early.
