Got a denial letter for unemployment, what now?, insurance claims processor here

My claim was denied after 14 weeks of waiting, and the letter says I have a short window to appeal. This is my first time dealing with any of this. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

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

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