Blue Dart Express — non-delivery of package within one day

I booked a package from mumbai to bangalore (With airway bill: [protected]) that i needed very gently and i paid for one-day delivery. However, your bluedart employees entered the wrong pincode for the address and the delivery was delayed by 2 days. Due to your delay i missed my deadlines and was unable to finish my urgent work for which the package was needed. When i spoke to your customer care executive, she rudely insisted that i myself had given the wrong pincode. Despite the fact that i repeatedly told her that i have a copy of the waybill and it very clearly shows the correct pincode so it could not have been my fault. Thereafter, i even emailed bluedart regarding this and i was told that they have taken corrective measures and that my package has been delivered. This is the worst experience i have ever had where you try to blame the customer for your mistake. When a package is delayed due to your mistake, the least you can do is be sympathetic to the issue being faced by your customer and not be rude and unhelpful. Further, i had requested for a refund of the one-day delivery fee because clearly no one-day delivery was attempted for me and to this, i have been told that i am not eligible for a refund because my package has been delivered. This goes to show how much faith one should place over the the delivery time committed by your company. I would advise everyone who requires urgent delivery of their packages to avoid your services in the future.
