Patethic service

I'm totally dissatisfied with Hyundai Lenasia. I bought a brand new vehicle, a Hyundai Atos in January 2020. Within 2 months the vehicles clutch gave in and it was taken to the dealer which they fixed. It's now 4 and half years later and the same problem has taken place. I do still have a warranty on the vehicle and now they refusing to assist me. The consultant I spoke to at the Lenasia branch says they unable to assist because the branch is under new management.
