Skoda India — very dangerous: tyres jam/sudden stop at high speed

We experienced a worst situation with so called 4*4 powerfull engine of yeti (Mh 46n 1139) it got stopped like someone applied sudden break when the vehicle was at a speed of 50kms on 20 apr 18. Wheels and everything jammed on its own and we tried to control to avoid slipping because of sudden stop. What could be my situation if vehicle was at 100kms/ hr. This is worst behaviour of a car. No one is resposive on 24/7 help also. Vehicle not moved an inch further. Total service done by skoda then also car faults create vey dangerous situation to the lives of people. Till date no one from skoda have courtesy to call back. Come and take ur car to scrap.
