Appeal deadline questions after an unemployment denial (Phoenix)

My claim was denied after 18 weeks of waiting, and the letter says I have a short window to appeal. I do not usually post, so bear with me. The letter lists a deadline and a hearing process, but it is hard to follow. Should I ask someone for free legal help?

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

Keep everything in writing and save the confirmation numbers. It saved me later.
