Blue Dart Express — services provided by blue dart are ridiculous

Address:

411006

Very important delivery of some of belongings were sent by blue dart courier on priority delivery (Which costed me 510 rs which is 5 times more than the normal rate)
Their courier boy came for the pick up and put the wrong pin code on their system while delivering it, got delivered after a delay of 7 hours from the scheduled time, and that belongings were sent to one of relatives who stays at usa for diwali, because of the late delivery the flight was gone and i could not send the same to my relative.
