FNB No service and no way to complain

Worst service ever. I tried to apply online as I am a existing customer. It will not accept my annual income as I am self employed. I tried the call center just to be transferred 7 times whilst none of the agents even tried to listen to what I wanted just transferred me. I got nowhere but upset and angry at the absolute disrigard for a customer. I should rater move my businesses elsewhere as FNB does not want to assist me. I cannot log a complain on their website as it does not give me a option to submit after tiping this whole complaint out. It is disturbig this is the ony platform I can put a complaint. Hopefully I get a response.
