Did Kia Motors Silverton de***** me?

Good day

I purchased a 2011 Kia Sportage on the 5th May 2017, At Kia Motors Silverton, I previously requested the invoice from a lady called Liezel Smith which I never got. I recently asked for the original purchase invoice and a settlement letter from Wesbank, I was surprised to discover the following 1. I paid for a tracker which was installed on the 3rd May 2017 without my permission, I wrote two emails to the dealer asking why and who authorized the installation? I never got an answer. 2. I was only made aware on the invoice that I paid for the service plan and it was not for free as it was explained to me. I also asked Why? No answer again. 3. There is a cristal fusion of R1899.00 which I did not authorize. Again I asked What is that? No answer as well. 4. There is a Fahims warranty of R7250.00 that I did not authorize, I also wanted to know what is that and what is it for? Guess what! No answer again. 5. I even attached part of their invoice that they send to Wesbank when I purchased the car to prove my case. 6. Basically I couldn’t get any answers from them whilst I strongly feel that they de*****ed me and took me for granted.
