Denied unemployment, how do I appeal? - any advice?

My claim was denied after 25 weeks of waiting, and the letter says I have a short window to appeal. 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.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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