HELP REMOVING "PAY WITH MY REFUND" CHARGE

when I filed my tax return I added the "pay with refund" option. The problem is that the IRS collected my refund so the payment was not made. I called customer support in order to remove that extra charge since I didn't use that service and told me they would send me an "updated" billing removing that 44 charge from my bill. I haven't received that email, so I called again and they made me wait 1 hour after I called them and they simply hanged up. I don't know what to do.
