Consumer Redressal

My Car was giving missing problem since the day it was purchased.. i raised this verbally during every service. after a year, it persisted and i again complained to Safdarjung Hyundai, in 2 and half years, my car has been to workshop 20 times and 4 times their mechanic came home. They did not check and repaired it thoroughly during warranty and now after warranty, they came up with a new problem of EMC being not OK and have charged Rs 30000. They deliberately did not check it during warranty so that they could charge Rs 30000 from me. I am paying out of pocket for a problem which has persisted for 2 and half years and could have been checked and repaired in warranty. They did not check my car properly deliberately therefore the problem recurred almost every month
