Hyundai creta - new hyundai creta with cheap kumho tyres

Dear sir, we have brought new creta from khanna dealers yamunagar in nov ****. They have provided us with cheap chinese tyres Kumho that have been puntured many times. Even one of the tyre got blasted. now everytime we go we are in fear that tyre will get puntured. dnt knw whether the company gave this cheap tyre or dealer has done this. we have complained against it to dealer and he told we have emailed to company but they are not replying. but in my view hyundai is good company and cannot cheat its customers
