multichoice de*****ing clients by debiting more

On the 20/08/2015 I received a sms notification stating that multichoice debited R806.87 with ref: Mchoice ***. My monthly premiums for my DStv is R339.00, for compact option. Comparison with previous debit orderes showed the following : 20/08/2015 M-Choice M-Choice *** R806.87, 20/07/2015 M-choice 33207 R339.00, 20/06/2015 M-choice *** - ***7 R339.00 , 20/05/2015 M-choice *** R339.00. August 2015 is more with R467.67. I request an immediate reversal, as i'm not in arrears with my monthly payment, this refund must be done ino the very same FNB account from where it was debited. Just a week ago i had to struggle for my Dstv decoder to be changed, because of system issues and incompetence, in less than a month another problem, my life is turned into a living hell. On record, multichoice together with their dstv outlets your office politics, systems upgrades and approvals,etc, is not client's problems. I want my refund A.SAP. this is *****. I want my money.
