Overpayment letter from the unemployment office - what worked for you?

After 8 weeks of benefits I got a notice saying I must repay some of it. I have read a lot of threads here and could not find my exact situation. The letter mentions an appeal window and a repayment plan. Are payment plans possible?

Read the letter for the appeal deadline and act on it, even if you think you will end up repaying. Then ask about a payment plan.
