Deducting on wrong date

Good day, I'm very upset. You keep on deducting before the 25th of each month. It was always after the 25th and all of a sudden you deducting like yesterday on the 19th?? And the best is today it show reversed?? There was enough money in for the debit order. Why did you reverse it? Now it is a bad credit record reflecting on my name because of reversal. If you don't change it i'll rather go to a other insurance company.
