Dell India — fraud in the name of offer

Address: 201016

I purchased my dell inspiron 7572 model, on 2nd jaunary from the dell site and on that time there was an offer going on which stated that on purchasing a laptop before 7 jan the customer will get a free senhiser headphone and after the laptop got delivered i filled up there offer form and waited for there reply. After some days i received a mail asking me for the missing information and i replied to that mail giving all the necessary information but after some days i received a mail stating that -
