What? No. You can totally talk to the IRS, and should, as they're the ones who know your situation. It looks like Optima is a tax service? You might owe them money for working with you, but they have no other power over you. All they are is a middle man that you were never under any obligation to use in the first place. If it were me, I'd figure out how to dump them and deal directly with the IRS.
