Debit order before the agreement date

I got approved for a loan on the 18/10/24 and today on the 26/10/24 I got a debit order of R231 but when I accepted the debit order the agreement was R269 on 28th of every month.Now I am wondering why I would get debited on a different date when the 28th is on a Monday?and why am I debited a different amount? Disappointed as a first customer and I regret borrowing money from you already, that's not a good start at all.

So since they debited the money they borrowed me within 7 days of loaning ,I wonder if I will still be debited again on the 28th?This is so frustrating
