Loyal client for years and then suddenly a R499 monthly fee

I tried to use the complaint section on the FNB website but it keeps on giving an "The response parameter is missing" error , so I decided that this review would be my next step.

I am a private bank client and never paid any monthly fees on my account because of the balance I kept above the specified amount , now suddenly with the new price structure I get charged R499 a month on my account , that is unacceptable. The response I got from my personal banker was that I need to qaulify for Ebucks and spend this and have an investment in this fund and lots of different stories for me to be able to qaulify for a better monthly fee , I really dont care for that and I am old school so dont want to be promised this for that and all the different chemes involved in just getting an affordable bank card I can use. I am unfortunately going to contact for the first time in 26 years another bank and see if I can do better with them , to me it is unacceptable to pay R500 bank fees for faciilities I hardly use and just to be able to keep my money in a bank. I was always a very loyal l FNB supporter and even got my whole family as well as friends over to FNB because of there good service and good security it is sad to me that it is going to end like this , especially because I have a substantial amount of money just lying in an account an trusting FNB with it. I understand I am probably not a good client because I dont use the products and dont have any debt and also dont use the overdrafts , but without our loayal customers I cant see a good future for FNB anyway.
