Hi Abubakar Sanusi,
As you mentioned, if there’s an overdue payment, follow the instructions in your billing section to settle the outstanding balance.

If you have paid all your bills and are still unable to enable your Azure account, I suggest raising a Support Request as shared in the steps below to resolve the issue.
1. Navigate to this link to start the process:
https://portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview
2. Click Create a support request button at top
3. If you see Support AI Assistant as shown below, click Switch to old experience button on right. If not, proceed to step
4. On left, enter re-enable subscription in the box and click Go
5. Select Subscription management and click Next
6. Select your subscription from the dropdown and click Next
7. At this point there will be a delay of several seconds, and then various options will be displayed. Click Create a support request button at the top. DO NOT CLICK any of the other options.
8. Fill out screen, Summary, Problem type: Re-enable my subscription, Problem subtype: Could not reactivate by self-service, then click Next button at bottom.
9. There will be another several second delay, and then some solutions will be displayed (this is similar to above). DO NOT CLICK any of the solutions, instead click on Return to support request button in upper left corner, similar to below
10. Now you are back at support case. Click Next button at bottom to continue to Additional details tab. Fill out information as required. Click Next to advance to Review + create tab, then click Create.
You should receive an automated email within a few minutes and then be contacted by support within 1 business day.
Feel free to reach out if you have any more questions—I’m happy to help
