The IRS has set the bar to an all time low with customer service. I mailed my ammended 1040X tax return priority mail next day delivery over 6 weeks ago. It's not even showing up in their system. You can never get a "Live " agent. I've sent at least 21 emails over 3 weeks and received no response at all. Nothing, nada, zilch! Where's the accountability? IRS, the worst customer service ever!
