Hi Kundan Ingle
Thanks for reaching out to Microsoft Q&A.
Your Azure subscription can get disabled because your credit expired or you reached your spending limit. It can also get disabled if you have an overdue bill, hit your credit card limit, or because the Account Administrator canceled the subscription. Some subscriptions can also get automatically disabled. See what issue applies to you and follow the steps in below article to get your subscription reactivated.
