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

I received a letter saying I was overpaid about $500 on my claim. Any experience at all would help. I did not notice any errors at the time. Are payment plans possible?

I asked for a waiver and a plan in the same call, and they gave me both forms. It was less scary than I expected.

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