Amended return

This whole tax year is an absolute disaster. Some how we marked some little box on accident, been fighting with the irs since February. FINALLY a was told to just amend our return after months of them telling me not to amend. Sent it in beginning of October. Online it says it was completed 11/12/21. When I call, naturally you can't get through. The automated system tells me something was mailed and I should have revived it by 11/12/21. We have informed delivery and there has been nothing from the IRS. Online it gave me a number with an extension code to call but they're either to busy it disconnects me right away or I sit on hold for literally hours and eventually get a "technical difficulties" message. I am so desperate for our taxes back. This is so ridiculous and I'm so fed up. It's been almost an entire year of this nonsense.
