Appeal deadline questions after an unemployment denial - any advice?

I was told my separation was for misconduct, which is not what happened. I am in Oklahoma City, in case local advice matters. The letter lists a deadline and a hearing process, but it is hard to follow. Should I ask someone for free legal help?

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

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