Denied unemployment, how do I appeal? after 6 years as a forklift operator

My claim was denied after 4 weeks of waiting, and the letter says I have a short window to appeal. I am in Atlanta, in case local advice matters. My employer's version of events does not match mine, and I have emails that show it. Did you bring documents or only talk?

Keep everything in writing and save the confirmation numbers. It saved me later.
