Hyundai selling defective cars and harassing customers

Bought this car in May 2023, still regretting why I bought this car. The vehicle started giving problem after 1 week. First the battery got drained in 1 week. After that the gear started getting stuck. Told the service center about both the issues while giving for 1st servicing, still the gear problem was not resolved. Again went to the service center after 10 days for recertification. They, assured it is resolved, but of no use. I am, chasing them to replace the vehicle, but they are Out rightly telling no it's not possible. After selling the defective vehicle, they have audacity to deny the customer and harass them. I, would not recommend anyone to buy Hyundai vehicles. Hyundai can never match Maruti.
