Capitec Debiting on the wrong date

I'm really annoyed and so ****ed off right now, agent disconnected our what's app chat ( Mbasa ) . Funeral cover was debited on the 15th instead of the 27th , i never agreed for the 15th, not all of us get salaries early in December and that amount was meant for something else. He told me to go to the branch for what?? Capitec Bank together with Centriq just debit funeral cover when ever they want, i want that funeral cover cancelled and reverse my money back.
