FNB changed my account without my consent

FNB clients be aware that my account with FNB was changed without my consent and they started charging me R480 a month banking fee for something I did not agree to. I have called them after this charge was made to correct this and I was told they have a backlog but it will be corrected before this month. Nothing was done so I called again and was promised someone will call me back and make sure this is corrected, but I did request the change. When I asked for proof the person told me she cant proof it but the system says so. I contacted them again making a complaint online and got a email that they will get back to me within 48 hours latest. Still nothing happens.... I will now raise this to the consumer protection commission as this is dishonest and I see the same has happened to others if I check the posts on this site. FNB clients be aware of this and check your banking fees!
