Overpayment letter from the unemployment office - 11 weeks in

I received a letter saying I was overpaid about $700 on my claim. Thank you in advance. 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.

Collect your pay stubs and certification records for the weeks they name. Mine showed the error was a date mix-up.
