Standard Bank debiting accounts on random dates

I have been a client of Standard bank for more than 20 years and they have ONCE AGAIN decided to debit my account on the 24th when the debit order date clearly states the 27th, leaving my account in a negative and this during lockdown. I logged this with them before when they randomly debited my account on the 12th of the month. Its a debit order that goes back to Standard Bank, so I would like to hear what their excuse is this time. So much for moving your clients forward. Think its time to move to a bank that has their clients' interests at heart.
