Hello Mohmed Taha,
Thanks for your question.
The various reasons why a subscription can be disabled and how to reactivate are documented here.
I would recommend you create a support request with Microsoft. I will guide you on how to create a billing ticket below:
- Go to the support page and click Create a support request. Like in the screenshot
https://portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview
3. On the right hand pane you will see a describe your issue. It will initially attempt to help use the assistant to help resolve. Type billing in the box and select billing then click next this will bring your subscription which you select. It will load up some items, scroll down to the “help+support” part and click create create a support request
Clicking this will take you to the support page.
After filling the first page it will try to recommend solutions for you, which since you want a support request and need assistance, do not click any. Instead wait a bit.
Then you can describe your issue and get assistance
You can mark it 'Accept Answer' and 'Upvote' if this helped you
Regards,
Abiola
