@HOCC2023 

Our main admin person left the company a few months ago, and she is listed as the contact. She is not available or willing to support in any way.

As long as your QBO account is active, Support will not bother offering any solutions. You may have 2 options:

1. Cheap but risky option. Ask your bank to block subscription payments to have your QBO account cancelled. Then contact Support to reactivate your account with the new Primary Admin credentials.

2. Purchase a third-party service to migrate your core data to a new QBO account.
