Hyundai Motor India — extended warranty not provided

Address: Bangalore, Karnataka, 560043

I have purchased xcent on 02/01/2015 with extended warranty but i been following up from january to provide but they hv not provided the same as sales executive is telling reason one or other to delay the same but when i called hyundai call center they said its not punched for extended warranty. I have no clue i should contact on lakshmi hyundai, hebbal, bengaluru to get this sorted.
