Very bad service

I have previously reported about the service of the client service manager at Home finance department. There is still money according to me that is outstanding to us from the COVID relief fund time. We have spoke and then he went on leave 26 March and still no answer from him. We are with FNB for years and really thought that this is the best bank. Well, I must say that he definitely changed my mind and if it goes on like this I am taking all my accounts and my husbands accounts to another bank.
