Overpayment letter from the unemployment office - 7 weeks in

After 7 weeks of benefits I got a notice saying I must repay some of it. I cannot afford to repay it all at once. Has anyone disputed one of these?

Keep everything in writing and save the confirmation numbers. It saved me later.

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.
