Hello ag ain twin,
I do understand how difficult it can be at times when dealing with the IRS. Once a mistake has been made (even on their end), it can take forever to get it corrected, and it is very frustrating. Unfortunately there is no quick or magical fix for this.
I have had many, many occasions where I needed to deal with the IRS on various issues involving errors, and I know from personal
experience how difficult it can be to even get through to the IRS by phone, and then depending on the representative you finally get connected to, your question may or may not be answered.
If this were me, I would personally try calling the IRS again --- maybe even 2 or 3 times if necessary. Hopefully you will eventually get connected to a rep that is willing to help you over the phone. If that is not successful, then you will have no choice but to write a letter to the service center where you filed his return, and explain in the letter the details of what has happened here. One other suggestion I would make is to go in person to a local
IRS office in your area. That would likely be a speedier process than trying to correspond with them through the mail.
