Debit order always processed at incorrect date despite debit order date agreed upon

<p>I have a credit card with FNB and when applying for the credit card, the agreed date for the debit order from my bank is the 1st of every month.</p> <p>However, FNB has been debiting my account by 25/26 of the month before the 1st day of the month as agreed upon per our contract. I have complained by sending a complaint on the FNB website and made several calls about 2 weeks ago and was told I would be assisted but after 2 weeks now, nothing has been heard.</p> <p>Is this how FNB treats its customers? What a poor service? Wont never recommend this to another person</p>
