Complain

I am totally unhappy with Hyundai dealership , we bought the car at Brystan and no one advised me that the service is for only 3 years and I've decided to take the car to Roodepoord branch , while i send them emails since June and no one responded my email and i send another email on 22/08/24 to make arrangements for friday to service the car , No respond until i call the on the 23/08/24 and i spoke to white guy it was exactly 17H00 and he told me to bring the car it was approved. In the morning when i get there they told me the car was out of service plan and if someone advised me was not gonna go there. During the day i received a whattsapp msg from the Branch telling me about windscreen had 2 chips and the car never went for inspection. Very bad service indeed and i am totally unhappy with how they treat the clients and my car need service which is costing me R4600
