Hello Jordi,

Thank you for posting in the Microsoft Q&A forum. 

I understand that you are having trouble on recovering your blocked account and are encountering a "Service temporarily unavailable" message when trying to receive SMS codes, and I can understand the frustration this has caused you over the past week. 

Your situation is clear that you can start recovery and get the first code via email, but the system then requires an SMS to your phone, and that specific service is failing. When an automated recovery method like this is unavailable, the path forward requires manual review by Microsoft's account safety team. 

Step 1. Review the Official Blocked Account Guide  

It is helpful to first review the official troubleshooting steps and reasons for account lockouts provided by Microsoft: 

• Microsoft account has been locked - Microsoft Support 
• Troubleshoot Microsoft account verification code issues - Microsoft Support 

Step 2. Submit an Account Reinstatement Request  

This is the official form for requesting manual review of a blocked or inaccessible account. It is specifically designed for situations where automated recovery isn't working. 

• Please complete the form here: https://www.microsoft.com/digitalsafety/account-reinstatement 
• Fill it out as accurately as possible. This is the most direct way to get your case in front of the security team. 

Step 3: Attempt to Contact Support via Live Chat 

If you need direct, real-time assistance because the automated systems are failing or if you have already submitted the Account Reinstatement Form without success, I recommend contacting a live chat agent for personal account support. 

1. Visit the Microsoft Support contact page: Contact - Microsoft Support. 
2. In the search bar, type "Account Recovery" and press Enter. 
3. Click "Get Help". 
4. Scroll and click "Contact Support". 
5. Select "Other Products" and then "Manage Account Security". 
6. Look for the option to "Chat with a support agent in your web browser". 
7. Clearly explain that your account is blocked and the SMS verification step fails with "Service temporarily unavailable." 

I appreciate your patience throughout this process. Please let me know how these steps work for you, and feel free to provide an update if you have further questions.
