Bad customer support

I was accepted at Boston City Campus so I wanted to proceed with my application and registration I’ve made numerous calls to get assistance but each time I call the campus I’m being passed around, the last time I called I was told the person who is supposed to assist me is busy and will call me back till today I’ve never heard anything from them I sent an email but still no response. I understand this time of year is probably the busiest but this is an inconvenience and I’ve thought of going to campus but I don’t want to waste my time because it seems like their staff have some knowledge gap they can’t assist with anything I am dissatisfied.
