Negligent every step of the way

I bought a Jeep from this dealership 2 years ago being told it had a full motor plan. They did the transfer but didn't give me my license disc so I got fined R500. Then last year I discovered that it wasn't a motor plan at all it was a warranty. They didn't deny that I had been misled. Smartly the guy said, let us sell you a car at a good price you'll really enjoy. They sold me a Mercedes with a motor plan to 160,000 km. They said they moved my tracker, they said they registered the car. In fact I caught them selling me a motor plan that had me paying in form 80,000. They fixed the motor plan. I had to phone four times for my license disc before they bothered to get it. And now 5 months later, it turns out that they didn't move my tracker across, they added a new one to the new car and kept the old one running in the car they traded in from me. Suddenly in December I got sms's overseas that my car was ****** only to find it was my old car. For the 5 months I've been double billed and they are dodging calls and sending me into long processes. They owe me R182.53 * 5 months. Next stop, the press and a lawsuit - *********** and dishonest all the way.
