WRONGFUL BILLING!!!!!!!!!!

I called Multichoice on 10 March 2018 to request that they disconnect my explora 2, as I was not going to be using it for that month. To my surprise/shock when I checked my balance on 17 March, it shows my explora 2 was still active. I called them immediately and was told that my explora 2 will only be disconnected on 2 April 2018. I requested to speak to the manager in charge, he said he will go and listen to the voice call and that I will be billed R111.00 for the week (10 March - 17 March), which I totally dont understand as I specifically told the lady on the 10 March that the explora2 should be disconnected with immediate effect. The second thing that made my blood boil is the fact that I should be having credit for the explora 2, as the premium was already taken on 02 March - Multichoice says that is impossible. I am very disappointed in multichoice and their customer care agents. this is **************** and I need multichoice to rectify my billing ASAP.
