Business account Standard Bank bad service

I’ve got a business account with Standard Bank, the service I’m getting is horrible , I’ve got a document I need from them , it’s been months trying to get hold of my banker to get me This document but no luck , even the Pinetown branch tried to intervene but still my issue still stands , no body cares . I’m applying for something and I need this document , it has closed already because I’ve chasing the banker non stop. This is so annoying because they are good with opening an account but after that you left high and dry.
