First Flight Couriers — delay in delivery and rude behaviour of the staffs

Address:

Agra, Agra, Uttar Pradesh, 282001

The courier containing medicines, was supposed to be delivered on 11 april at my office address.
But it was not delivered till 2:30 pm, so i called at the first flight courier office sanjay place agra. When i asked about my courier, the person whom i talking told me that today is strike so we cannot deliver your courier. I requested him again and again but he disconnected the call. After one hour i called again and then some other person picked the call and said that collect your courier from the office. As the courier was containing medicines so i have to pick the courier from the office. When i reached the office at 7:45 pm i saw there were five people gossiping. So i was shocked that how irresponsible they are because at the top of my courier it was written that this packet contains medicine.
