Bad attitute

I have a Standard Bank Revolving loan account since 2012. I called the call centre and spoke to 5 different consultants who could not assist me with a settlement quote, they just kept on transferring my call the next person who could not assist me. The last consultant advised me to obtain the settlement quote from the branch as they are able to give me the correct settlement amount. When I got to the branch after standing in a queue for about 15 minutes I was advised to provide my ID document of which I became very annoyed as I was not advised by the call centre agent to carry my ID to obtain a settlement quote. I informed Bongani that I just need to settle the loan account he can verify my details as I know my id number of which he refused. I then asked to speak to his manager, the manager/team leader (Setembiso Gumbi) just ignored my request and Bongani also igored me and decided to walk away. My concern here is that I need to settle this account however Standard Bank refuses to assist me in this regard. I am really disappointed and appalled by the service I received today
