Bad Service

Upon purchasing a new Hyundai H100 cash from the Lenasia branch,my service book was altered by the sales consultant(he scratched out the 10000km,20000km,40000km sevice intervals) .The vehicle accumulated mileage more then the required interval and upon taking my vehicle to get serviced i was advised by a service consultant to bring it when it reaches 30000km. Now that it has reached its interval i booked it in but to my surprise i was told that it does not hold its warranty .This service is pathetic as well as it is misleading.I also spoke to the principal dealer which was no help to me. Had i known this was the case and how Hyundai treats its customers i would have never purchased a vehicle from them. I dont want any thing for free but good service goes a long way. I am aware that Amith Singh no longer works there but Hyundai is responsible to take care of their customers
