Got a denial letter for unemployment, what now? - what worked for you?

I was told my separation was for misconduct, which is not what happened. I do not usually post, so bear with me. My employer's version of events does not match mine, and I have emails that show it. Should I ask someone for free legal help?

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

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