A very angry customer

In December 2018 I bought a Volvo s60 T3 2014 powershift, from this dealership. After trading in my Mazda 2, 1.5 Dynamic, I was assisted by Shakes Mopasi the sales person. Since I bought this Volvo I never had a peace of mind, the car was due for service when I bought it. In January 2019 I took the vehicle to them for a major service of 160000 kilometers, but they only did a oil change as per request of Shakes Mopasi. In February 2019 the car had the problem with the engine, I took it back again. They said I might be the sensors, they tried to claim from the warranty but the claim was rejected. Due to the service that was not done properly, in April 2019 I took the car back to them again. They allegedly changed the engine, of which I'm not convinced, the car was with them till May 2019. Until I took it in June 2019 the engine light reappeared again, I took the the car back to them again. They tried to claim from the warranty and the claim was rejected again, they allegedly fixed the car. In Sept 2019 the engine light reappeared again but I never went back to them. In March 2020 my gearbox started leaking due to lock down they were closed, In June 2020 I took the car back to them, they told me to pay 80000 for the gearbox. But I did not have that money, in August 2020. I took my car from them, as we speak the engine that was allegedly replaced is having a problem in less than two years. And I can't claim from the warranty because of the incorrect service, and the missing service records. At the moment I've taken the matter up with MIOSA, the past two years of my life have been a living hell because of Imperial auto volvo Bloemfontein. I would never encourage anyone to buy cars from them due to my experiences.
