Address:

Mehsana, Gujarat, 382715

Dear Team, my name is Rahul,
I have applied for passport for my sister whose address is Ankleshwar, so I required documents copy with original so
My uncle had booked documents from Ankleshwar to Kadi with name of my cousin Nishit Dave by Tirupati Courier service with AWB num[protected] and[protected] on 17th Apr 2017, after a week courier is not received so I contacted them three to four times but they did not give satisfactory answer, finally when I asked the status at head office Rajkot, they told that they have missed and lost the same and unable to find the same.
I requested to find and deliver for same but they told that it's my mistake that I have send the documents.
Request you to please help the same as I have appointments at passport Seva Kendra on 27th April 2017
