Denied unemployment, how do I appeal? after 5 years as a web developer

My claim was denied after 7 weeks of waiting, and the letter says I have a short window to appeal. 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 last year, and it settled down once I kept a simple log of every call and form.

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