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 a software tester. Thank you in advance. My employer's version of events does not match mine, and I have emails that show it. Did you bring documents or only talk?

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.

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