India Post — Delivery Taking so much time

Address:

21-2-102/3, Markandeya Colony, near Hanuman Temple, Siddi Vinayaka Line, Godavarikhani

Hi,
I have sent a document to USA(Arizona) on May 21, 2022 with Reference no: EN[protected]IN, although the mentioned delivery period is 4-10 days, its been more than 15 days now, the item is still in India showing the tracking as Send receptacle abroad (Otb) in Delhi Airport. It reached Delhi airport 3 days ago and its still showing the same status. I raised a complaint against the delay in delivery - [protected], but its showing the different tracking details. I tried to follow up with Indian post customer service, they said they don't have any info and gave me Delhi post office contact number, no one is picking up the call. Its like no one cares about this..Please take an action.
