Debit order on the wrong date

Good day<br> <br> I am very upset as I have requested on several occasions that my account not be debitted on the 19th of each month because there will not be any funds available to honor the payment. I have had to pay bank charges in the past due to the debit order going off against insufficient funds and have notified you of this on two occasions before.<br> <br> You dont seem to have noted my request or just don't care. I want a refund of the charge of R90.00 and will also rethink my decision of continuing to be your client. You are laughing all the way to the bank and someone like me have to pay for your incompetence.<br> <br> I am not going to take the responsibiltiy of covering the charges for your oversight. I want the bank charges to be refunded and should I decide to stay with you, I want your written confirmation that no debit will go off on the 19th of each month.
