Appeal deadline questions after an unemployment denial - 12 weeks in

I was told my separation was for misconduct, which is not what happened. I have read a lot of threads here and could not find my exact situation. 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?

Thanks for writing this out. I went through something close to it 10 months ago, and it settled down once I kept a simple log of every call and form.
