Gross incompetence an inconsideration of clients

Unfortunately there is no zero rating, which would be more appropriate. I have a car loan with Nedbank since January 2025. As per paperwork submitted, my salary date is 25th of each month. Nedbank however, decided to debit my account as and when they please, at huge inconvenience and finance costs to me. I called them this morning, after they again debited my account, despite my Debi check mandate being for 25th, spoke to Mahlatsi, whose explanation is that Nedbank does this sort of campaigns, and a lot of people who get paid on 25th are in the same boat. No solution or recourse offered. I then asked to be transferred to someone senior who would be able to resolve this as I don't think I will survive 5 years of this incompetence. Mahlatsi then says he is transferring me, only to put me back on queue where I have to again listen to the same menu I had just listened to. Someone should pay my bank fees, offer a formal explanation with apology, and hire a sound system management process. .
