Hyundai sold me a s**** car, now I'm suffering from depression because of it

I bought a car in February 2024, they struggled to get bring me it's number plate, few days after I bought it started showing the handbrake even if it was down, the sales person said it was not a problem I should take it to the nearest Hyundai, I didn't get any help... The permit expired I had to use a public transport, so I couldn't take the car back to them for the handbrake no communication from them. They brought another permit and I took the car back to them and left it there, the car was even more damaged when I got the number plates they told me it was not warranty related fault I had to pay R4000 something to get it fixed, the car was less than 2 months in my possessions after a long battle with them they agreed to fix the issue without me paying, I fetched the car, a year later I can't reverse the car and I sent an email to Hyundai to ask if the car was still under warranty, they said yes I took it to Hyundai Lenesia they told me that the car was in an accident I told them I had never had an accident they said there were signs of it and I should pay R3500 for it to be diagnosed the problem is with the clutch and it is not warranty related, their technician was in a hurry that he told me that I should book for the car and disappeared... My partner tried to explain to them that I was there for the clutch but for the gear linkage that is broken, the service manager went to check it out and saw the broken part, told me that it has been broken for a while I surprised coz the car was working fine until Monday 9 June 2025 and they would not sell me a car like that, maybe I should take it to Hyundai East Rand where I bought it... Im very disappointed with Hyundai I'm thinking of giving it to them... I don't think I am going to fetch the car now I have had so many problems with the car more than I expected
