Poor service

I have been a very loyal FNB customer for many years, but the last 2 months dealing with FNB has turned into a nightmare. My credit was due to expire end of May 2021, I could not get service from a branch and had logged numerous online queries. Eventually I decided to upgrade my account as one of the persons who I spoke to in all of my adventures advised me that I would get better service being a Premier account holder as I pay more in fees. The long and the short of it is , that it costs me double in fees and currently my credit card is again not working.... And all I get from FNB is sorry for your inconvenience but not anything to rectify their mistakes!!!! Terrible customer service, think it is time to switch away from FNB.
