Debit order deducted before the agreed date

Absa deducted money from my account (that I urgently needed) for a debit order BEFORE the date. Upon contacting the collections department I was informed that the deduction does not yet reflect and I should phone at 12:00 then they will do a reversal which I understood to be immediate as no mention was made about a waiting period.

Upon phoning later I was informed by Samantha that I would need to wait between 3-5 business days despite informing her that I required the money URGENTLY and that my agreed date for debit orders is the 1st of each month as I only get paid on the last day of each month, taking into account the 1st is a public holiday, the money should be deducted on the Saturday 30th of March 2024 (a day of the week Absa has deducted before) or Tuesday 2nd of April 2024. She informed me that I should have received notice from Absa to state the money will be collected today (which I did not receive), the only notice I received was AFTER the deduction this morning.

When querying if I could change this date to ensure that my salary is paid before they deducted I was informed I should have changed the date 7-10 working days prior to today, how am I to know I should change the date if I was not informed the money would be deducted today. I am very unhappy as I was met with a response of "you need to inform the complaints department"

I request that the amount deducted be refunded into my account BEFORE close of business today 28 March 2024, as you are fast to deduct but slow to refund.
