Quickbooks Problem that is worse after contacting support

We upgraded to Quickbooks Desktop Plus 2022 and were able to update all of our company files.

Upon then beginning to work, we attempted to create a State Unemployment Wage File which first accesses Excel and then connects to quickbooks.   In all of our company files, while attempting this, we got an error message that Quickbooks couldn't connect to Excel.   We followed all suggestions given and it did not correct.

We then contacted Customer Support and were told to contact Customer Support - payroll.   We got a call back and spent over six hours on the telephone while the agent moved files and things around on our computer.  At the end of the six hours we had company files in the correct location and an additional location folder she created called TEST.   Additionally, in one of the companies, she could not get the payroll data reconnected.

During this session Quickbooks was uninstalled and reinstalled two times, the File Doctor used endlessly and we were finally told it was being escalated.   We heard nothing and called at noon today to be told it was improperly escalated and the case had been closed.

We know someone with more technical experience will need to call and log on the machine with us.  It seems to be impossible to get this to happen.   Any advice?   We have a deadline today to file unemployment taxes for several of our companies and we have to begin processing a payroll.   We need action today!   Please help!
