Hyundai Motor India — engine got seized within warranty period

Address:

Khordha, Odisha, 751030

I have purchased hyundai excent dated on 31/5/17, vehicle regd no. Od-02-al-8967 from utkal hyundai. I did time to time service. But few month ago i have noticed about leakage of coolant. There after i checked in the service center and they changed the regulator and said now it's completely ready to use. But now my vehicle engine got seized and they are not providing any service and saying you have to pay for the parts where as my warranty period is there. So i expect your sympathetic action regarding my problem
