Told I owe money back on my benefits - what worked for you?

After 5 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. I did not notice any errors at the time. 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.
