FNB - worst bank

There should be a negative rating for this one. I have been trying for 2 weeks to correct an incorrect charge on my account due to a bank error and after spending hours on calls, emails and on the banking app help channels all they have managed to do is delete another transaction that had nothing to do with the issue which has now resulted in my account with a 3rd party being suspended due to non payment. I can't get a hold of anyone to assist me and just keep getting bounced between departments. Even dealing with the complaints department has yielded no results. FNB your service is disgusting.
