Renault Gave Me a Faulty New Car and Failed to Resolve Ongoing Issues

My problem is with Renault. The brand-new car I purchased in September already had issues from day one—I went home with a broken key. I reported this to the service center and the sales consultant, but they blamed me for it. However, the sales manager said, "I'll take care of it," and sent me off. Two months later, I was informed the replacement key had arrived, so I went to the service center. While there, I also reported an issue with the fuel gauge. They said the car would be ready by evening or the next morning, and I agreed. That evening, I called to say I needed to pick up the car because my child was sick, but they told me they had just started working on it and discovered the dashboard panel was burned. They then offered me a replacement vehicle. Initially, they sent an old replacement car at 8:00 PM, which they later replaced with a different one the next day. This car, too, was full of issues. I tried to use it for a while, but by the second day, the rim was bent, and the tire was swollen. I visited the service center twice to request another replacement and finally managed to get it changed after persistent efforts. But does the problem end there? The replacement vehicle started showing maintenance warnings as well. Despite explaining that I carry children in the car, no one seemed to understand. You can’t even provide a proper timeline when I ask. I’m now planning to email Renault in France. Please return my car in proper working condition, or I will escalate this to the Consumer Arbitration Board.
