You can create a new QBO company, and close your current one. A few things to note for this option:
When you cancel your QuickBooks Online subscription you have read-only access to your QuickBooks Online data for one year after you cancel your subscription
If you’re subscribed to QuickBooks Online, you can export data to Excel or to a desktop version of QuickBooks up to a year after you cancel.
If you’re using a trial version, you must export within 90 days after you cancel.
If you decide to go with a new account, and your current Chart of accounts isn’t part of the issue, you can move it to the new account. Here is a link to walk you through the steps: Move your Chart of accounts to QBO
