Appeal deadline questions after an unemployment denial - first time posting

My claim was denied after 10 weeks of waiting, and the letter says I have a short window to appeal. It has been a long 10 weeks. My employer's version of events does not match mine, and I have emails that show it.

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 saved me later.
