If you are the admin then you can reach out to 365 global customer service here.

If you are the only global admin on the account and are blocked entirely, you can reach out to the Azure / 365 Data Protection team to restore access. 866-807-5850

Also, for the future, you can create an emergency access account (break glass) in Azure AD. This account will help prevent being accidentally locked out of your Azure Active Directory (Azure AD) organization because you can't sign in for any reason. https://docs.microsoft.com/en-us/azure/active-directory/roles/security-emergency-access
