I'm exhausted

We buy cars tried to fix the vehicle more than 3 times but the problem is still persisting hence they refused to cancel the deal from 2024-01-30 to date. After writing my first review they tried to escalate the matter but right now I always have to call to get feedback on the cancellation. I'm spending more money on transport as I'm paying for the vehicle which was in my possession for less than 5days since the day of purchase. It's very hard dealing with this people. All I can think about is we buy cars lately and I'm even on the edge of loosing my job
