FNB Private Clients

I was advised to upgrade to FNB Private Clients in order to qualify for a better interest rate on my home loan. I went ahead and upgraded. Biggest mistake!!!!! The first banker I was allocated never responded to any emails or messages and I was allocated a second private banker. Things were going alright and when I tried to contact the banker a few weeks ago (during office hours), there was no response, despite him being online on WhatsApp. I sent another message, but no reply. On 6th July 2022, I phoned the Private Banking Suite to ask what the next step is and whether I can get another private banker (shocking- 3 in the space of 4 months) because I'm essentially paying for a service that FNB are not providing. He said he'd send off an email requesting a new banker. On 14th July, I followed up as I had not heard anything. The person I spoke to said it takes about 7 working days but she'd send off another email and escalate it. Today, on 18th July, I still had not heard anything. I phoned the Private Suite again. The lady said she'd need to check who it was that I had phoned the first two times and put me on hold. For 45 minutes, I was on hold, using my airtime. I eventually had to put down the phone and I phoned again. This time, the person said the same thing and I said I will not be put on hold again and that she must phone me back. It's been 3.5 hours of waiting and I have still not heard anything. This is the worst service I have ever received from FNB. I have always been very happy with their service in the past, even advising my parents to switch over, after they had been with their bank for more than 20 years. I cannot believe that I'm paying for a private client service and I'm not even getting close to what I signed up for. FNB, you should be ashamed of yourselves. Also, I'm at my wit's end and genuinely don't know what more to do.
