I did that. I've called them twice. I sit on hold around an hour just to get someone with a whole lot of attitude no answers and telling me to email <a rel="nofollow" target="_blank" href="mailto:incometax.processing@dor.ga.gov">incometax.processing@dor.ga.gov</a>. If there is no way of knowing why didn't you just say that? I'll have to call again.
