Frustrated and Disappointed

I purchased my vehicle in October 2015, and from the beginning my contract was messed up. The manager at Hyundai Cresta Jeremy Challis told me that I have tracker but to my surprise I did not have it, I had to call around and follow him around for weeks to ensure that tracker was installed. Imagine if something had happened. 2. My Mileage on the contract was incorrect and I have to constantly remind him to rectify them over and over but he is not taking me as a customer seriously. 3. My maintenance plan policy is also messed up and I have been trying to sort it out and Jeremy keeps ignoring my calls and emails. This is really an inconvenience on my side, and following a dealer around is not something I want to do everyday. I am supposed to be enjoying my vehicle but instead I have to follow Jeremy around to sort out my paper work. I am literally drained and disappointed.
