Got a denial letter for unemployment, what now? (update)

I was told my separation was for misconduct, which is not what happened. Any experience at all would help. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

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