Bank reconciliation

I have deleted my bank recs with the help of Sage support. They were not supposed to wipe out all my bank recs.  I told Sage I did NOT want to back up and reset anything I just wanted to restart March (was not posted) So I do not have a back up to open. 

My question is :

My last posted bank rec was Feb 2022. I was told to go to start of fiscal year (nov 1 2021) and start....2nd person at Sage said to start in January. 2022. He also said if I don't match still to adjust my start and end balance. However I can't do that. ?

I just need to start again the correct way.
