Hello Aditya Raj,
Thanks for your question.
To do this:
- Go to the portal. portal.azure.com
- In the left-hand menu, select “Help + support” and from there locate the Support plans section.
- here you will find your current support plan listed, click on change
- Select the Basic (free) support plan. Confirm and that takes you to free tier
If you cancel an Azure Support plan, you're billed for the rest of the month. Cancelling a support plan doesn't result in a prorated refund. For more information, see Azure support plans.
