Crash your car????

I am driving a 2014 polo 1.4 Hatch that I wanted to trade in for a new Polo or second hand but with a sun roof and screen display radio. I call VW Strijdom Park Volkswagen and they sent me a sales person to assist with the quote for my old car to see if they will buy it for how much. Two days passed with no respond I then gave the a call and was told that an email was sent to me. I told them I did not get such an email. Sylvester (sale person) who took my quote was the one who was handling all this and he told me about the email. I then asked what was the reason for the long respond he then told me that they could only take my car for R50,000. I asked why so low and was told it was due to my previous crash that I had 2015 on my passenger door. He then advised me to take my car and crash it to a tree so I can have my insurance pay. I ignored what he said and proceeded with a better solution. He then came back to the same story of me crashing my car to a tree he even added that I should not get hurt while doing it. I call the manager Allan Stiles who told me my car could be around R70,000. He then referred me to a manager at used cars who told me he can take it for R110,000. He told me to drive to the shop on Saturday 25th for us to get a deal done. I stay in Norkem Park and had to drive 72km just to be told that he thought my car was 2015 model. All this time they had my car details on the system number plates and also pictures. Do I really need to say more? I am so angry and thought I would be driving a new car by December. Is this your sales strategy?
