Bluedart — parcel delivered to wrong address

Address:

Hoshiarpur, Punjab, 146001

My parcel got delivered to the wrong address. I came to know about it when received e-mail that your parcel has been delivered. What else can i expect from a courier company. I called them multiple times but they do not pick the phone. Such a pathetic courier service. My expensive goods i ordered by paying a handsome amount just destroyed by the bluedart. What steps i can further take?? Please tell me
