India Post — My Speedpost has not been delivered yet even after 4 weeks

Hi,
I sent few documents to USA on 28/07/21 and they haven't been delivered yet, its been 4 weeks now the status shows the shipment hasn't moved from IGI TMO New Delhi after arriving there on 05/08/21. I am unable to register to my classes unless the university receives those documents. The delay/ failure of India post might cause me lose my semester/admission. Can you please lookinto this matter and delivery it ASAP. The reason for going with speedpost was for faster/reliable delivery.
