  1. It’s RIDICULOUS that it’s darn near impossible to schedule an appointment with them by dialing the appointment line phone number. (1) When the call goes through, I’ve left messages and my number for someone to call me back, but no one ever does (2) The majority of the time, a recording comes on, claiming I need to call back later or the next day, to which I get the SAME RECORDED MESSAGE. From my experience in the army as a base tax center non-commissioned officer-in-charge and trained tax preparer, this is NOT proper customer service.
