India Post — article not delivered to wes even after 25 days

Address:

H.No 10-5-790/A/2, Sainagar,North Lalaguda, Tukaramgate, Hyderabad, Telangana, 500017

I have booked a speed post for my certificates on 7th december 2019, which are to be delivered to wes (Canada).
And till today its not delivered, its been 25 days. As per india post norms a speed post must be delivered in 5-6 days and when i call to the customer support they just enter my tracking number and inform the same status which i can check at my end too. They have no escalation matrix, they cannot connect to their higher officials. They have no update on their application.
