@Mohamed Diallo - Welcome to Microsoft Q&A and thanks for reaching out to us.
Apologies for the inconvenience caused to you.
If your country is not listed when creating an Azure account, you may need to contact Azure support for assistance.
- Go to the Azure support page and select the type of support you need (e.g. Technical support, Billing support, etc.).
- Select the subscription that you need help with.
- Fill out the support request form with your contact information and a description of the issue you are experiencing.
- Click on the "Create" button to submit the support request.
Azure support will review your request and help as soon as possible.
In some cases, Azure may not be available in certain countries due to legal or regulatory restrictions and at that time you can try creating a new account in a different country or region if that works for you.
Hope this helps. and please feel free to reach out if you have any further questions.
