Hello,

I am reaching out for urgent assistance regarding an issue with my tenant.

I accidentally processed a B2B conversion on the only account that had administrative access to the tenant. As a result, I am now completely locked out and unable to sign in.

Because I no longer have access, I am unable to shut down services, and the tenant continues to incur charges. I attempted to contact support by phone and was advised to create a support ticket. However, when I try to submit a ticket, I receive authentication errors and cannot proceed due to the same access issue.

At this point, I have no way to access the tenant or open a support request through the standard channels, and I am continuing to be billed.

Please advise on how this can be escalated and resolved as soon as possible. I am happy to provide any additional verification or information needed to regain access or terminate services.

Thank you for your urgent attention to this matter.

Kind regards,
