Hello Pratikshya Das,
Thanks for your question.
It may possibly be a case of you needing to switch directory. You can switch directories in the portal by selecting your account name and then choosing Switch directory. it is the "settings" icon in your screenshot
If not, you will need to most likely contact Azure support
You can mark it 'Accept Answer' and 'Upvote' if this helped you
