Sad client service for a first time buyer

very sad experience with the cape town branch. We saw a car we liked and approached the dealership. The gentleman confirmed that the car is available and if I do the finance with them he can fight for a good interest rate ect, I decided to do my own finance that took me a whole day. the bank confirmed all in order ect and called them for an invoice. the next day I had to call them just to hear that I must do the finance with them and can't do it myself, (wasted my time ad could have told me all the terms the first day on the inquiry) agreed to get the same interest rate, I sent application form only after that I not sent the pictures of sc****s and damage to the car and that the car last service was in 2016 last. that was still fine but then I received the finance approval just to see and extra R20000 has been added namely a tracker +-R4600, service cost to get the car to my name R4800 and a 2-year warranty of R8850. When I enquired about all this I was told all is compulsory except the tracker. this was not mentioned beforehand. today my hubby called them and asked questions and all he was told is that all this information is on their website and there is nothing they can do. When hubby said then we will not be taking the car the reply was fine the sales guy will just remove the sticker from the car. Very very poor client service, I am very disappointed.
