Poor customer service and reaping us off

I actually trade - in my car with the April 2025, I asked for a detailed copy of my contract Chelsea and Mfundo are giving me 100 excuses, the left side mirror for the car I got it's broken they haven't fixed it. Every time I call Mfundo he doesn't answer my calls or sometimes take almost 3 to 5 days before he could respond. Another annoying thing is that I when I was given the car I had an incident where I locked the car keys inside nd I went to my place to get the spare keys to my surprise the spare key doesn't even open the door nor does it start the car.,i brought the keys back to them to fix that until today it's not fixed. I reported my challenges to the manager it fell on deaf ears. I have asked for certain documents to cancel my old car insurance I'm being send from pillar to post. What a poor customer service these people have shown me and I don't even like this car anymore. They treated me like a joke after the deal went through because all they worried and care about is my money. I regret why I bought the car wish I could return it. I'm ****ed I've been quite for long and hoping they will fix they problems. It's a mess. I hate Hyundai Pinetown
