First Flight Couriers — Stolen goods in transit

My consignment no. MJ2742097 was dispatched from First Flight couriers, Kapoorthala, Lucknow on 23.08.2013 . It was suppose to be delivered on 26.08.2013 , but was delivered late on 27.08.2013 on my Gurgaon address. When I received this insured consignment, I noticed that two toy cars were stolen from it .In transit, the goods were taken out and taping was done again which no one could have noticed while taking delivery. As soon as I noticed it, I brought it to the notice of First Flight, Kapoorthala, Lucknow. They reverted by saying that we should be happy that everything else except for the toy cars has been delivered. They misled us, gave us wrong contact numbers and kept us in dark for a week. Finally I wrote a mail to First Flight, Faizabad road, Lucknow and Gurgaon offices expecting a reply. I had a word with Ms. Kanak and her senior female official Ms. Shivani (from Faizabad road, Lucknow office) who gave me verbal assurances but no complaint was registered and no complaint number was given to me. I submitted a written application along with proofs (courier receipt and cost of toy cars) to the Branch Manager, Mahanagar, Lucknow. Still no complaint no. was given to me. So far, despite constant follow ups no satisfactory reply has been given to me and I am highly disappointed by the way an aggrieved customer is treated.
