Private client service is pathetic

I’m a private banking client with FNB. Have been with the bank since I was 13 in the old BOB smart card says. Since March I have been seeking assistance from my private banker. He failed to meet numerous appointments and when he did attend- he’s assistance was pathetic to say the least. Escalated a complaint. Got a call from a poor guy who is an analyst and not even a private banker. A week later and his boss has not been able to refer another private banker to me? Despite me following up and emailing the head of department to call me urgently- nothing from FNB. I called the service department today who said I need to escalate via the app (agin???). I’m sick of this run around. During these terrible financially insecure times, you would expect your bank to help you and advise you. Not FNB. Change your slogan guys. I’ll be moving banks.
