So tired of FNB

I have a loan with FNB. I got a notification from FNB that my loan will be deducted on the 15th. I have been trying since the beginning of the month to change this as I still get my salary as normal. I haven't been able to do this. I sit at reception and can't be on the phone half the day. To try and communicate via their secure chat is pointless as I was in line for so long, i eventually got cut off. I have also requested FNB to change the debit order to the last day of the month, because that is when i get my salary EVERY SINGLE MONTH. What is frustrating is that you think you can just assume we all pay earlier in December. Maybe in the future, contact the client and make them choose, find out when they get paid. My frustration with you is reaching a boiling point. Luckily, within the next to months, I don't have to deal with you anymore.
