Poor service and misleading information

I bought a brand new Ford Ranger 2019 from Lazarus Ford Centurion and had very bad experience from the beginning. First of all my Bluetooth was not working even after taking it back to Lazarus Ford Centurion numerous times. Only after the fourth attempt they fixed the Bluetooth in my car however the staff that worked in my car made it so dirty that their was stains I could not get out on the roof. Secondly I bought the car on the Ford Guaranteed buy back option after the salesperson guaranteed both myself and my father that their is no residual value or balloon payment on this option. We made it very clear we did not want an option like this. A year went past I called Lazarus to make sure that their was no residual value option on my car and the FNI confirmed that there wasn't. According to ABSA I would have to settle R 230 000.00 after the 5 year period which basically is a residual value. Ford conveniently changed the residual value wording to a buy back option. JUST A FRIENDLY WARNING TO FIRST TIME BUYERS BE VERY CAREFULL OF THE BUY BACK OPTION AT FORD dealerships.
