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

I received a letter saying I was overpaid about $700 on my claim. 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?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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.
