Osmania University — Final degree Certificate showing as Issues but never received

I have been trying to apply for my final degree certificate of B.com computers but the status on the official website is showing as already applied/issued though the certificate is never applied or issued or received by me. and my hall ticket number is showing as unauthorized too. I have applied for the final degree certificate on urgent basis by applying 3500+ But cannot see any progress in the status. I have paid hefty amount for fast service as I required the document on urgent basis for visa purpose.
