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

The agency says I reported earnings incorrectly, but I think I followed the instructions. I would rather hear the honest version than the polite one. I did not notice any errors at the time.

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

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.
