Overpayment letter from the unemployment office after 3 years as a janitorial supervisor

I received a letter saying I was overpaid about $450 on my claim. I do not usually post, so bear with me. I cannot afford to repay it all at once. Who should I talk to first?

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.
