Early debit orders

This is very frustrating.I feel like closing my account with Fnb for good.I haven't even gotten paid yet but my home loan instalment went off.It's lockdown and i need to manage my money carefully and i can do that by myself.My debit order order date is suppose to be for the 25th of each month.So where in the hell does the 24th come in.Awaiting a bull**** explanation.
