Blue Dart Express — product not delivered within expected time frame though price paid was high!

Firstly when i contacted bluedart before even processing anything you gave me a charge of rs.850 by road and expected time as 5 days. When i asked if we can reduce the travel time, bluedart confirmed that it can go by air and will reach the destination in 1 or max 2 days and the charge would be rs. 2500 (Which is almost 3 times of that of the road).

In spite of paying this heavy charge, shipment took 4 days to reach and the receiver has left the location and travelled to mumbai. Now i would want bluedart to ship the package to mumbai as they have failed to deliver within their promised date.

Note that i could have chosen an alternate service provider to deliver the same package in the same timeframe for just rs.400! Please let me know how bluedart can fix this!
