Denied unemployment, how do I appeal? - 19 weeks in

I got a denial letter last week saying I left my job voluntarily, but I was let go as a retail manager. I have read a lot of threads here and could not find my exact situation. The letter lists a deadline and a hearing process, but it is hard to follow. Should I ask someone for free legal help?

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.
