Dissatisfiying finance assistant

I am quite disappointed on how they fail to assist me as an existing client to bank better, I had credit card and I never missed my payment until I closed it and I also have a home loan of which I have never default in payments but for some reason that even appeal to a long term client they just decline my other finance application yet other banks I don't work with are willing to assist. I think they can do better especially to their existing clients
