Pointless call centre

I am consistently unable to talk to a call centre agent, despite the number (808) being on all correspondence, and on the web. After a couple of minutes, you just get disconnected. Apart from the time I have had to invest in driving to Morningside to resolve an issue, it's just plain rude! And annoying. And a disgrace. What's the point of a call centre then? Please don't tell me how sorry you are and it's a one-off thing. The staff in Morningside tell me everyone is complaining. So please just DO something. And while you're at it, please contact me so that I can ask you one little question pertaining to my email documents. Thank you.
