Blue Dart Express — blue dart express pan card returned to nsdl rtos

Address:	New Delhi, Delhi, 110017
Website:	www.bluedart.com/index.html

I have applied for pan card by filling the form 49a i didn't get any call till today from courier service or concerning the delivery of my pan card (Ayrpb2298q).
Immediately with the given airway bill number ([protected]) i checked at buledart website to track out my status, but they have returned to nsdl rtos already on 22 sep 2017. There was no call from blue dart express till date and no one came at my door from blue dart even. I was very much available for those days.
Thus, i kindly request you to take this complaint as serious and grant me to have my pan card at the earliest
Thanks
