Appeal deadline questions after an unemployment denial - 13 months and counting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a data-entry clerk. Thank you in advance. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

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

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.
