Denied unemployment, how do I appeal? - first time posting

I got a denial letter last week saying I left my job voluntarily, but I was let go as an electrician's helper. 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?

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

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