Blue Dart Express — Delivered bank related paper wrong address & to a different person

Address:	560061

I had requested a bank statement on ivr and after couple of days i checked with bank on the delivery status. They provided the reference number [protected] & informed blue dart is the doing the courier. I called blue dart & they confirmed it was delivered and person who collected was "rakesh". From 7th i have been following up with them as it emergency for me get those bank papers. Every time i call them they say some one will call back within 30 mins and i haven't received any call back nor update. My question is how can they hand over a bank papers to someone else and not to the person mentioned to. Are they only worried about getting rid of the package or do they take responsibility of making sure the package is delivered to right person.
