Blue Dart Express — irresponsible delivery schedule and declaring my non-availability without contacting me

Dear madam/ sir

It is regarding airway bill no. [protected]

On december 6th, i was told that my delivery would be attempted on the same day. So, in the anticipation the delivery, i postponed all works which include my thesis and day off my department and library.
At the end of the day, the courier updated that i was not available - i hope you see the irony of the situation. Let me tell you, i was available - i think i was never more available.
What is more disgusting is the lie which was updated for a reputed service like yours.
Would i be using your service and spreading a good word about you - well, its depends on your course of action.

Thank you.
Yours truthfully,

A highly dissatisfied consumer of yours,

Vikash
