HP India — I purchased gift hp wallet worth rs. 3000 but didn't receive yet after 40 days

I purchased hp wallet worth rs. 3000 on june 17th and i was supposed to receive the same by july 17th. I mailed them and they asked me to wait for another 10 days and i waited. Still didnot receive the gift. Product serial number is cnd6469rpd. I am flying to the usa this weekend and i am not in possession of this and i lost 1998 inr because of the company's fault. Even after contacting them many times there is no positive response from their side
