Blue Dart Express — courier service - delayed in spite of high charges and loss to me

I had submitted a courier for sales documents of my car to trivandrum on urgent basis through blue dart on 25th september 2017. They assured me delivery within 48 hours since sales had to take place of my vehicle.

Today being 29th, the courier is yet to be received at trivandrum address which resulted in cancellation of sales and loss of money to me.

Waybill no is [protected]. I want to claim compensation for the damages caused to me.
