Worst service with new car

I am at my end.<br> <br> I Bought a new Jeep Renegade last year October. I drove it a few days and there were a problem with the cluster. They took it in, took 3 months to get a new one, only after I complaint it took so long. Got the car back, but now the Speedo is in Miles per hour, so I don't know at what speed I am driving in km. Send them photos, but nobody is talking to me. <br> <br> I WANT THEM TO TAKE BACK THE CAR, I will find something else with better service.<br> <br> Feeling very let down and angry. The car only has 2000km on it.<br> <br> Elma Marais
