Fnb bank brairdene

Please advise how can i report a consultant at fnb bank branch brairdene durban. My husband account was debited twice from uber eats first debit we ordered and payment went off successfully then few days later uber eats debited him again and there was no funds in his account keep in mind his account is not allowed for over drafts so it went on a - balance once he got paid the money was taken and his being to FNB for the past 3 weeks specifically the team leader silindle zondi who has absolute no customer service manners and absolutely terrible attitude towards my husband as she can't help with this he must go to dispute department after showing fnb brairdene branch for 3 weeks all the proof they cant explain where the money has gone and refuses to help him. Im disappointed with how they carry the bank name as my husband has being with FNB for many many years he is now gonna close his account and bank else where but i want to know what will be my step going over because this is not right people can *****ly take money out our account and we must just ignore it we work for our momey not to be treated in such a manner.
