In most countries or regions, billing support for Microsoft 365 for business products and services is provided in English from 9 AM-5 PM, Monday through Friday. Local language support varies by country or region.

Admins, have your account details ready when you call.
Note
To better protect your organization, we added a PIN-based verification step to our existing phone-based verification process. If you contact us from a number that isn't registered with your organization profile, the Microsoft support representative sends a verification code to the registered email or phone number in your Microsoft 365 admin center profile. You must provide this code to the support representative to grant them access to your organization's account.
If your country or region isn't listed above, use the sections below to find the support information for your country or region.
