Unsatisfactory service - FNB Private Client Banking

I've been an FNB client for nearly 20 years now. As a Private Banking Client, I'm extremely disheartened with the level of customer service or rather the lack there of. I've been trying to obtain information from my private banker since 15 September 2021 and, even after multiple follow up calls and emails, I've had no success. Today, as I was trying to follow up yet again, my email got rejected and her number is out f service. When I called the service suite I was advised that she no longer exists on the system. I don't see the sense in paying for a service that does not exist.
