Hi Russell,
I truly understand how frustrating this situation would be, as after being told the issue was already fixed, you have to face the risk of losing your business data.
For a proper review of the charge and to request a refund if applicable, this will need to be handled directly by Microsoft’s Billing Team, as they are the only team with access to billing records and payment methods.
With that in mind, the best next step is to create a support ticket and submit a billing inquiry. The billing team is best positioned to investigate the transaction, confirm whether it is a duplicate charge, and advise on any available refund options.
When submitting a billing request, clearly referencing your intent to request a refund can help facilitate accurate case routing. For instance, you may consider a ticket title such as: “Billing Support Request: Refund for a duplicate charge”
For guidance on how to request support in the admin center, please refer to: Get support - Microsoft 365 admin.
Note: If your account does not have administrative permissions, you’ll need to contact your IT administrator to submit a support request on your behalf. In case you do not know who your IT admin is, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support
