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

After 3 weeks of benefits I got a notice saying I must repay some of it. It has been a long 3 weeks. I cannot afford to repay it all at once. Are payment plans possible?

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

Thanks for writing this out. I went through something close to it 6 months ago, and it settled down once I kept a simple log of every call and form.
