Dear @Syed Ahmed,
Thank you for posting your question in the Microsoft Q&A forum.
For better understanding your questions, could you please verify that you want to cancel Microsoft planner Plan 1? Besides that, please provide more detail information so I can support you effectively:
- Which Microsoft account are you using when you access Planner? (Personal account or business account)?
- Did you purchase yourself or it is unexpected charges from Microsoft? In case you need to investigate a billing charge from Microsoft you can follow this article How to investigate a billing charge from Microsoft
Looking forward to your update.
