Hi @
Thank you for asking this question on the **Microsoft Q&A Platform. **
If you are the tenant admin and have been locked out, you should raise a support ticket with Azure.
Global Support Phone Numbers - https://support.microsoft.com/en-us/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2 (here you can find the number of the support teams of your region)
If you are not the admin, contact your boss ang give to him/her this imformation.
Hope this helps!
