Denied unemployment, how do I appeal? - any advice?

I got a denial letter last week saying I left my job voluntarily, but I was let go as an event coordinator. I do not usually post, so bear with me. The letter lists a deadline and a hearing process, but it is hard to follow.

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.
