Has anyone ever gotten an answer from Assisted Payroll on a Tax Notice?

I got a tax notice from a state asking us to pay interest because a tax payment was made late. We have Assisted Payroll, and Intuit makes tax payments on our behalf. There is no way to pay this on our own, since they have the account. I called assisted payroll, and they explained how to submit the  notice. That was a month ago, and I have followed up multiple times for them to say that they never received the notice. I offered to send it to the person on the phone, but they say they cannot accept it. This is BEYOND frustrating!

Has anyone every gotten a tax notice successfully addressed by Assisted Payroll (and found out why they were late making payment to begin with)?  What did you do to get a response from them, and the notice addressed?
