They swap vehicle parts

Last year I took my car to Hyundai Strijdom for service. They did all the checks everything was fine. Early this year had a problem with sunroof, I took the car to Strijdom again. When the car was there I received a tracker notification that battery was disconnected. Didn’t pay much attention. This year I took the car to a different Hyundai dealership for service, when they were doing checks, they realised that the battery was of an incorrect size and it wasn’t Hyundai approved battery. Beware guys. Those guys are bunch of ******.
