Shocking. Shocking. Shocking

I am disgusted on the service received with the dealership... They literally brush you off once you drive the vehicle out of the dealership... It hasn't even been 24hours of having the vehicle Range Rover Velar which cost an arm and a leg, the 1 headlight stopped working and the dealership wants nothing to do with it... I wanted to speak to the owner and was told that the owner doesn't deal with any clients... What a load of nonsense... I am shocked that the dealership is still operational and I don't understand how they approve the cars through roadworthy...
