Bad service

I Mr PT Khuboni not happy with fnb services. I went to FNB Randfontein branch at Village Square On the 31st December 2021 to down grade my Private client account to Gold Cheque account. The person who assisted me she assured me that the account is successfully downgraded she even made amendments on my account that even appeared on banking app to show that it was successfully downgraded . To my surprise end of January 2022 they deducted the private account monthly fee and no one called me from FNB to explain what's happening with my account , I then personally called fnb and asked how can they deduct the private client monthly fee when I went to the bank last year to downgrade my account instead they told me there is nothing the can do from their side I have to go to Randfontein branch and speak to manager by myself which I fail to understand why they didn't resolve the matter internally since I already went to the bank in December last year. Instead after few days they assigned me a new private banker. However I explaining the same story, which He seemed as if He understood. To my surprise yesterday on the 15/02/2022 they debited half amount of the private client fee for the services that I have never used and worse part that I asked them numerous times to cancel but they failed to. When I called them to enquire no one seemed to care instead they told me that's s how they operate. This shows that fnb doesn't care about clients financial state instead they care about making money. This is so unprofessional, time consuming and costed me lot of airtime and frustration. If they don't fixed this it leaves me with no choice but to cancel every account I have with fnb including my wife's accounts. I am truly not happy, disappointed.
