That is frustrating.  I had a similar situation when I wanted to update to Quickbooks 2024 (not Accountant) and was not able to do it on my own.  I was given a number to technical support.  They told me my files were corrupt and I had to pay to have them repaired.  I got this technical support phone number from a Quickbooks agent on a chat.  The number seemed to belong to an outside vendor who wanted to charge me big money to fix my files.   I was very uncomfortable and got off the call.  I called another agent and got the assistance I needed to just do an update from 2023 and 2024.  He was very professional and new the difference between an update v. upgrade.   I wish I had the chat available to submit to someone because clearly QB has employees giving out false information that could result in wasted money.   I was able to update my file with no additional fees/no corrupt files.  We pay a lot for horrible customer service and constant sales pitches.
