Appeal deadline questions after an unemployment denial - first time posting

My claim was denied after 15 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. 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.

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