Worst bank ever

I have logged a complaint with FNB in November 2021 already Complaint Reference *** assigned to eBucks, the only response I keep getting is that the complaint is forwarded, and nothing happened until I kick and scream, I get told they are investigating , still nothing happens. I have not been receiving e bucks but my salary goes into this account, i buy from the places they say, they keep insisting that i have an outstanding one month loan since 2020, and i keep sending them the same proof of paid up account, hell I still take these loans on a regular, I dont need this account anymore, standard banks reward system is far better. I hate this bank , FNB sucks at customer service I have had nothing but bad experiences with them. I know im not going to get a response, Im used to it already, but if by some luck, i don't want to speak with them telephonically, i want a response in writing
