Famlies first help?

Years ago, our family signed up for Families First to help with money every month, but since then, we are no longer getting help from them, and eventually paid off some kind of debt to the state for 2,000 dollars, but they have taken several thousand, but still say we owe them 2,000. This is seriously illegal and scammy, and I don't know what to do, especially with no money. The father's stimulus check was garnished due to child support not being paid to us, and was granted to us, but the state took it like they keep going. Help?
