India Post — EH[protected]IN - Skullcandy Bluetooth Neckband Earphones

My consignment (EH[protected]IN ) was sent on 16 th May from NFL Post Office, Panipat to Skull Candy Service Center at 201, 2nd Floor, Chandra Bhawan, 67-68, Nehru Place, Delhi-110019.
Online it shows item is delivered to Kalkaji Post office on 20 th May, 2022 but till date it is not received by the scull candy Service center. I am calling kalkaji post office but nobody is receiving the call. My Neckband Bluetooth ear phone will cross it's warranty period in some time so it's urgent for me to clear this.
