Most frustrating bank I have ever dealt with.

Once again I have the same issue . I would like to get assistance with advice on how to take further action against a big industry as such. I cannot keep on fighting with this bank regarding honoring fees which are clearly UN-justified and down right theft . This is an on going issue and I need further assistance as it is pointless to go into a branch or contact their so called help center . We sit on calls going trough departments and still no assistance what do we do as consumers?
