Wrong debit order dates!! Not my Fault when u move earlier!

Dear FNB i really dont know where to start, i really brag about fnb everywhere i go i love you guys, first off i have personal loans with you and when loans where taken up i asked for debit order on the 25th of each month, the past 3 months you gladly decide to start taking on the 24th of each month, without consent and now my company doesnt care if its saturday or sunday that falls under the 25th but thats when we get paid we do not get a day before or after our paywe get it the 25th, now everytime i log into the app for almost a week it shows my loans are in arrears?????but the debit order did go thru and shows on the loan satement aswell, please fnb this is bad for my profile with you,please check i never skipped a payment but when i said 25th i meant 25th not the 24th please could this be urgently corrected i do not want late payments on my name not due to my salary date. or please move the date further, i tried phoning for this but really cant wait 45min on a line???????
