Got a denial letter for unemployment, what now? - 5 months and counting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a warehouse supervisor. The letter lists a deadline and a hearing process, but it is hard to follow. Should I ask someone for free legal help?

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.
