Overpayment letter from the unemployment office - 12 months and counting

The agency says I reported earnings incorrectly, but I think I followed the instructions. It has been a long 13 weeks. I cannot afford to repay it all at once. Who should I talk to first?

If you are unsure, free legal aid in your area may help for this kind of notice.

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