The worst service ever!!!

This dealership doesn’t even deserve 1 Star, i’ve just put it because i’m prompted to do so. I bought a car from them in June 2021. According to the service book this car was serviced on the day i picked it up 30 June 2021. On 3 Mar 2022 the car was giving me problems. This was hardly a year when i had it and i made the management know and they (apparently) serviced it that day and confirmed its ok. Today 1 Mar 2023 it’s going for its second service and it comes back with a diagnosis report with a balance of R27652.66. Why didn’t they do this diagnostic on the 1st service day which by the way it wasn’t even due because i took it in due to its problems. Even before 9 months of driving that car i could sense there’s a problem that’s why i called them to check it. This was a bad deal, as a single black woman i was taken advantage of because i don’t know anything about cars. My mistake was trusting Joey Stiglingh for telling me it’s good car and he actually gave his word because there was another one i was interested in prior to settling for this one. This was a ford fiesta and with that one he confessed that it looked like a cut and joint and will give me problems later. I canceled that deal thinking that i’m getting a better car actually a good car as confirmed by Joey. Only to find out i’m being fooled. I’m going to take this matter with my attorneys and will not let this go till something is done because another poor single mom will fall into the same trap.
