First Flight Couriers — improper delivery of my packet to MYAS delhi

Address:

Gwalior, Madhya Pradesh

sir this is to bring to your notice that i had sent a very important envelope with documents for a post i had applied for at the MYAS shastri bhavan from gwalior by first flight courier on the 3rd feb evening .This was dropped in the post box of shastri bhavan on 6th feb after 3 days and that envelope never reached the concerned person to date .This is a very big blow for me and i plan to go to court as i have missed a very big chance of my lifetime.The person who was to deliver it instead of delivering the packet to the officxe of the concerned person hass dropped it in a the post box like a postman.What is the difference between your courier and a postman.Obviously i have spent alot of money with full confidence that it will reach the destination but the last date was 10th of feb and i have missed it am attachiong a copy of POD INDU MAZUMDAR lnipe Gwaliior
