i need support for my 365

For Microsoft 365 support, the phone number depends on whether this is a business subscription or a personal/home subscription.

• Business Microsoft 365: admins can use phone support. Use the current country/region number from the global phone numbers list. If the country/region is not listed, use a neighboring country/region or the United States support number. Before calling, have the account details ready. If calling from a number not registered in the organization profile, Microsoft sends a verification code to the registered email or phone number in the Microsoft 365 admin center profile.
• Business online support path: go to the admin center at https://admin.cloud.microsoft, select Help & support, then Contact Support, and choose Phone or Email. The expected wait time is shown in the Contact support pane.
• Personal/home Microsoft 365: use the Microsoft Support contact flow. Enter the problem, select Get Help, then Contact Support. Available options may include chat or a callback depending on the issue and account.

If this is a business account bought entirely through a partner, support must be requested through that partner.
