Hello Kritika,

Here are some steps you can take:

• Contact Support: Reach out to the support team of the platform or organization where you submitted the preference. Use their helpline, email, or support portal.
• Submit a Grievance: If the platform allows, raise a ticket or grievance mentioning your issue clearly.
• Visit the Office: If possible, visit their regional or main office to request the change in person.
• Check Deadlines: Ensure your request is within the allowed timeline for changes, if applicable.
• Follow Up: Regularly follow up until the issue is resolved.

Hope it helps !
