Denied unemployment, how do I appeal? - first time posting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a hotel front-desk agent. I would rather hear the honest version than the polite one. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

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

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.
