Extreme Bad service

I am extremely dissatisfied with the after-sales service at Lexus The Glen. In my 30 years of driving different types of vehicles, I have never experienced such bad service. On Monday 18 November 2024 we saw an error message on the vehicle: Stop/Start malfunction, take the car to the dealership. We did it immediately. They checked and said nothing was wrong with the car. An hour later, after filling up at the garage the vehicle didn't want to start. Long story short, the car stays at the dealership until Friday 22 November 2024. That is 5 days without E-hailing business. Everyone doing e-hailing will understand how frustrating that is. On Monday 25 November 2024, I received the same error message and I drove straight to Lexus The Glen and almost forced the dealership to sort out the mess. They sent an email telling us that they could not find fault with the vehicle. That mail was sent around 11 a.m. Around 16:20, I called to find out what the update was just to hear about this particular mail. How would we have thought they would communicate via email? Secondly, is it not customary if you see the receiver doesn't respond to call the client to find out what's happening? I'm writing this review withholding all other details for later. I want to give Lexus The Glen a chance to explain why they treat us like we are not important. Just the fact that we bought this vehicle at Lexus itself and receiving this kind of service is excruciating. I logged a call at the customercare Lexus South Africa and I dint receive any feedback from them up until the time,e of writing this review
