First Flight — forged commitment

Address:

Cuttack, Odisha

A letter was booked on 23/10/2012 from new delhi to cuttack through first flight courier ltd. bearing doc no- MD0243989.
i was promised to get delivered on 25/10/2012 and i paid rs 150 instead of paying normal courier charges(rs 20) for a single letter delivery because that letter was v.v urgent for me.
now my problem is that on 25/10/2012 when i called up on cuttack office for letter delivery they said that letter has been despatched from new delhi and we can't trace where it is right now and the same answer i got on 26/10/2012.
If someone pays rs 150 instead of rs 20..what does that mean?
I[censored] people can't deliver letter in 2 days why the hell u commit and claim to be best courier service?
Till now i haven't received the letter and im suffering a great loss coz of that undelivered letter..
This is the worst courier service in india and these courier peoples take unnessary charges for letter delivery and the letter which they deliver can easily and quickly delivered by any other courier service and that too in rs 20 only...
