Frustrated and unhappy customer

Planet 42 car dealership has the worst customer experience. Never buy from them. I bought a car from them on 23 April 2024 a Mercedes A*** and took delivery of the car on the same day. You test drive the car in the parking space and I then agreed to sign the contract for the car subscription to start making payment in May. I took delivery of the car and the car had problems immediately while driving home. It started showing the transmission problem orange message. I took the screenshot of the car and reported it to Clement who works for Planet 42. I was then told that I must bring back the car. The car key also had stopped working on day 2 after taking delivery of this car. I took the car back to planet 42 and was told it needed to go for assessments. Its been almost 2 weeks without a car. I am currently using uber to go to work and back. When I follow-up with Planet 42 and the workshop. I am told Fleetbuddy warranty still needs to approve the repairs. I am without a car for the 3rd week now and my work requires that I travel to see clients. Planet 42 does not care. As long they debiting R9500 from my account every month for a 2007 old mercedes that is malfunctioning. I will change my banking details from this month and ensure they dont get a cent from my hard earned money. I am very frustrated and no one from this company seems to care. I regret entering into a contract with a company that's so *********. I wish I had the CEO/ Director details to send a detailed email expressing the bad service I have received from this company. The worst service experience in my life.
