Hyundai Cheating customer and very poor service

All this Bad review I am giving due to poor service of Hyundai and the pathetic service center at Bhadrak. Bought Verna on January -22 . April post few thousand Km run within four months. Car head light got internal cracks. I have logged complaints at the showroom of Bhadrak. Where I bought the car. From last two months they are turning around me and making me fool. Even call the Hyundai customer care and logged a ticket too. Pathetic none had called me from Hyundai till now. Spent 15 lakh buy a vehicle from them and they didn't even called back for 15 days. Pathetic service and cheating the customer.
