Change my debit order date to the 24th

My account is in arrears because of Capitec unhelpful staff and also rude. Last month I called Capitec telling them my salary is paid into my account on the 24th of each month. This is the second month now they debiting my account on the 23rd and yet I told them I am getting paid on the 24th.

Now I have to pay bank charges for unpaid debit order. I have told you I don't know how many times I am getting paid on the 24rh afternoon.

There's money in my account now and you not debiting yet I told you to debit on the 24th afternoon. This is tiring as it cost me money and I regret borrowing money from you guys really.
