Tax Table Update

After being on hold to the IRS for 37 minutes (complete with obligatory musical serenade) I have been shoved into some sort of white noise that feels suspiciously like I was pushed off the 'on hold' grid.
What should I do?
Press 0?
Hang up and start over?
Keep waiting?

Tax Table

According to our tax preparer, we owe a lot of money to the IRS. So much so that we set up monthly payments and are currently still working on paying it off, estimating that we may still be paying by tax time next year.

Imagine our surprise when we received a letter stating the amount we owed was actually less than a third of that amount.

I'm on hold to the IRS right now to double check that I've read everything right. While I'm on hold I have plenty of time to eat breakfast.

A verse comes to mind:
"You prepare a table before me in the presence of my enemies."

Remaining in hope that "goodness and mercy will follow".
