There could be several reasons why you haven't received a call from DSPMU yet:

1. Application Review Process: The university might still be in the process of reviewing applications. This can take time, especially if there's a large number of applicants.
2. Incomplete Application: Ensure that you have submitted all the required documents and information. Any missing details could delay the review process.
3. Eligibility Criteria: Double-check if you meet all the eligibility criteria for the program you've applied to. If you don't, your application might be rejected.
4. Communication Delays: Occasionally, there might be communication delays or technical issues that prevent the university from contacting you.
5. Shortlisting and Selection: The university may have already shortlisted candidates for further evaluation. If you haven't been selected, you might not receive a call.

Here's what you can do:

1. Check Your Application Status: Contact the admissions office at DSPMU to inquire about the status of your application. They should be able to provide more information.
2. Follow Up: If you haven't heard back after a reasonable amount of time, it's worth following up with the admissions office. A polite reminder can help expedite the process.
3. Be Patient: Remember that the admissions process can take time. It's important to be patient and persistent.
