Creta Cluch cylinder failure

Hyundia Creta is a faulty Vehicle and it clutch fails at few kilometer drive. The baisc issue is the upper and lower cylinder of clutch which fails and then they change your full clutch so that they can avoid warranty norms. Cylinder is basically covered in warranty and clutch is not covered under warranty. As the vehicle is in warranty and they need to replace the cylinder free of cost but they change your whole clutch and will take handsome amount of money from you saying that you did not drive the vehiclke proper and were driving with half clutch. Actually it is a faulty vehicle and it clutch cylinder fails and instead of covering it in warranty they change your whole clutch so that they can charge you for the same. I am driving car from last 15 years and never have seen such issue in any car or such behaviour of cheating customers after selling the faulty vehicle. Do note that the isssue is not with clutch but it is with the cylinder.
