Dstv ******

i paid to have my dstv packages reconnected on 9/9,from then till 21/9 it was connected then i got message saying i had outstanding payment for packages i added i went on app & saw that multichoice did reversal of my payment on 9/9 & used that money to pay premiums on dstv waiver insurance i took out couple of months ago but i assumed lapsed which was fine with me. so ****ed off because how can they reverse payments with my consent. i paid dstv who hell gives them right to pay premiums. they reversed dstv payment 9th but they let me view till 21st before asking for payment.why didnt they disconnect dstv same day for non payment or ask for payment sooner because due date of payment they have 9th.they ****** because they know that if premium not paid they cant demand payment so they reverse dstv payment let me view knowing that when they ask for payment i would have to pay it because its owing to them. probably thought i was idiot. im sure what they did is not allowed. who do i contact to make formal complaint
