First Flight Couriers — product not delivered even after 11 days in same city

Address:	122001

My shipment was dispatched at Gurgaon Udyog Vihar branch on 4th Oct and today is 16th Oct but not dispatched at My House which is very near.
I have connected many time over phone with the First flight team but they are not responding. Please let me know why I paid for first flight and following for shipment.
I could have gone for other courier service also if you provide this type of service.
Medicines were in my shipment and my father was required urgent so we selected first flight so that we can get at proper time.
I discussed with Shop owner who sent this medicine and he said that now we can not use five injection because it should have been kept in Fridge within five day of dispatch.
I have lost injection worth of Rs 5000/- .
Who is going to take responsibility for this.
I will file case against first flight for my Money and due to medicine we faced problem and my father who is 65 years old and suffering from illness not got medicine at proper time.
