Bad bank FNB

Good day I'm a business banker at FNB I might not have a million dollars company and not make a lot of profit due to I don't want to bank rob my clients. I rather have my clients returning to me time and time again. My problem is FNB blocked my account without informing me been a week calling and emailing back and forward and they can't resolve a small matter. FNB doesn't care how much business you as one of there clients losses due to they bad service. I'm running a lost of R4500 FNB owes me shows in my account but it's on hold for almost a year and until today they refused to realise my money even after me and the client went and do as they requested to realise my money. I use to recommend FNB to so many different people but I'm at the point where I think my business is not good enough and neither my money for FNB. I'll love for the highest person in FNB to contact me to resolve the matter other wise I'll take my business to a different bank because I bank that can't sort out clients doesn't respect there business neither there money.
