Post Office Nangloi[protected] — Speed post not delivered

Address:

B-722/25, Ambika enclave,Nihal vihar, Nangloi, West Delhi, Delhi-110041

I have tracked the consignment ID (ED[protected]IN) of the speed post, it has been delivered to the Nangloi post office on 15th June 2021 but it is not yet delivered to me. The postman is constantly denying of having received the post. He is not delivering the post even when he has it. It is causing me problems as the post contains my appointment letter and I need to send it back to the head office after signing it before 23 June 2021. We have faced such problems in the past as well. This post man named 'Arjun' is very reluctant and lazy to do his work, and as a result a lot of our tasks get affected.
