Bad After sales service and wrong commitments

I bought a mecerdes 2017 model C220D from them last month(14th July 2021) and I was assured that all the inspection are done properly and that the car has a spare key. AFter the car was handed over ,the very next day I found that car's heated seats are not working and informed this to dealership. I was also not provided with the spare keys. They asked me to book the car for checkup at Mercedes.Merecedes have found out that there is problem with electric circuit and they would more days to analyze and check. I have also found out that Automated Parking is not working due to same reason. So,Basically within month of buying an expensive car ,I am sitting at home without a car and have to use uber. Just because they didnt do AA inspection on it as they claim they have specialized Technicians with them,which couldnt find the issues.
