The benefit, as you've explained it, is to cover certain bills. Those bills were covered.
You are whining that, even though you received the full benefit, you didn't get to pocket a windfall at taxpayer expense. The sole basis for your belief that you are entitled to such a windfall, as of yet, appears to lie in your imagination.
You are free to consult and attempt to retain lawyers to represent you. If you are serious about this, start doing so. Given that your case appears to have no monetary value, I would expect that any lawyer you find will expect to be paid by the hour.
