Hy,

here are a few steps you can take:

1. Check Your Email and Admission Portal : Ensure you've checked all communications from the university, including your email and the DU admission portal. Sometimes, roll numbers and other important information are sent via email or updated on the admission portal.

2. Contact the Admission Office : Reach out to the DU admission office or the specific department where you were admitted. They can provide information on your roll number and any other admission-related queries.

3. Visit the University Campus : If possible, visit the campus or the relevant department in person for assistance. Sometimes direct interaction can resolve issues more quickly.

4. Check for Updates : Keep an eye on any official notifications or updates on the university’s website or official social media channels.

5. Connect with Other Students : You might also find it helpful to connect with fellow students or join student forums related to DU. They might have similar experiences or information about how to handle such issues.
