After you file

I don't see how this is legal. How can IRS keep tax returns this long with no correspondence to the tax payer? I'm on day 83. I have called numerous times. I filed a SAMS. I filed for an advocate. I've called more. I'm just told to wait longer. I've asked for error code and im given none. Every time i call i get a different answer. Seems like an attorney is the only way to get any answers at this point.
