engine failure and denial of warranty

I owned a fiat linea emotion in the year 2010 and i also took extended warranty for 4 years which ended on oct 31 2014. My engine got complaint so early at 60000km because of the dealers poor servicing though i had given for servicing at prescribed time periods. When i gave the car to rectify the complaint they told it need an engine replacement and they would try to cover it in extended warranty. After a week they called me up to inform me that the company has deliberately refused for warranty aince i ve given the car late for my third service approx few weeks. And they wanted me to pay 95000 rupees for the correction of engine. I tried contacting them after that but they never turned up. Silly reasons they make to cheat the customers and make money on fake promises like extended warranties which they charged wxtra while buying. Morover this car company has the worst of services and customer obligation. An engine failure at 60000 is a failure of the company. Single user of the car and never drive rashly or with bad fuel. Iam cheated by fiat indi
