How to loose your money to the magicians

In January 2018 I took delivery of the car I bought through imperial Toyota city. When I went for test drive in December 2017 the vehicle was good. Little did I know that I get myself into trouble. Toyota automark did not disclose to me that the vehicle sunroof is not standard something that will affect my warranty plan I only noticed this on the booklets upon delivery. They promised to supply me with my extra key and dekra report to date I have not received those documents. They don't reply my emails they call sometimes. Now that it has been raining I notice rain is coming through the drivers door now it makes sense that the vehicle was once involved in an accident and this was never disclosed to me. I see claim documents from previous owner which I suspect it was for an accident on the passenergy side. Previously I told the sales men that the vehicle drives funny and I took the vehicle for wheel alignment with RMI approved mechanic cause it looks like the car hit the pothole when they gave it to me. The same potholes story could be confirmed by the mechanic because the tyre had a bump. We spoke about this bump and funny driving and I have email trail and calls to the dealership complaining to this day no one has assisted me. Makinor called me two weeks back to conduct a survey and I told them about my dissatisfaction and they promised to escalate the matter to this day nothing has been done. I warn people to be careful of this formal big dealership who promise to deliver the best service and quality products. I realise small dealerships out there would have supp**** me with better products for a reasonable fee. Their F and I increase his amounts on the day I collect the vehicle. He is sending emails using colleagues email address which seem ***** from the start. I regret the day I bought the vehicle through imperial if I went through other dealerships all of this would nor have happened. Failure to assist me now with what I bought will leave me with no choice but to seek legal recourse since they are testing my patience
