I have tried to purchase Microsoft 365 Business Basic several times, but I encountered an issue and was unable to complete the order. I received the following error message:

"Something happened. Validation of your order failed. Please contact support for assistance."

I attempted to follow the instructions to create a support ticket, but there was no form available for me to submit my issue. Only a phone number was displayed.

How to fix it?

Thank you

    Hi @Pitsanu Polsri,

    Welcome to Microsoft Q&A forum.  

    Thank you for reaching out. I understand how difficult it is to repeatedly attempt purchasing Microsoft 365 Business Basic only to receive the message “Something happened. Validation of your order failed.”

    This issue typically occurs when Microsoft’s automated verification system cannot complete the required checks during the order process, or when there is a temporary problem with browser sessions, account details, or payment validation.

    Based on what you've described, this issue likely involves your billing profile and subscription records, and will need to be reviewed by the Microsoft Billing department to ensure everything is correctly linked and processed. 

    The best next step is to contact the Billing team directly through the Microsoft 365 Admin Center. By following the steps outlined below, you can easily submit a support ticket and get the assistance you need to resolve the issue.    

    1/ Log into admin.microsoft.com with your admin credentials. If you don't have admin permissions, you'll need to contact someone in your organization who does.  

    2/ Select the green help & support button typically located at the bottom right of the admin center dashboard. Click on it to open the support pane.    

    X Help & support Search your Give Feedback

    3/ Type in “I need to purchase Microsoft 365 Business Basic but the order keeps failing” into the search bar. 

    4/ Select “Contact support”.      

    5/ Choose your preferences: preferred contact method, preferred time zone, and preferred contact language.

    If you are encountering the error message "Something happened. Validation of your order failed. Please contact support for assistance" while trying to purchase Microsoft 365 Business Basic, here are a few steps you can take to resolve the issue:

    1. Refresh and Retry: Sometimes, simply refreshing the page and trying the order again can resolve temporary issues.
    2. Check Payment Information: Ensure that the credit card information you are using is valid and matches the country you selected during registration.
    3. Contact Support: Since you mentioned that there was no form available for submitting your issue, you can try contacting support via the phone number displayed. Make sure to have your account details ready when you call.
    4. Use the Admin Center: If you have access to the Microsoft 365 admin center, you can navigate to Help & support and type your issue in the query box. If the results don't help, you can select Contact Support to get further assistance.

    If these steps do not resolve the issue, you may need to wait for a response from support after contacting them directly.
