Worst service

I bought second hand mazda at the dealer have to deal with dishonest sales person when handling the car over to me it was missing lock nut then he said is the rule of their dealership you take it as it. I got bad service from Sir- Bastien, and many other fault that i had to take the car to nearest mazda at polokwane and pay for 360 point check and ive never refunded that money.
