Bad service to possible new client

I inquired about a second hand vehicle advertised on Cars.co.za from Hyundai Strijdom Park on 22 October 2018. The dealer (Ian Caw) contacted me the morning of the 22nd. I was told that the vehicle advertised did not have 1500km on as the advert stated but 18 000km. This already proved that something is wrong. I gave the dealer the details of my VW I wanted to trade in, and was told he will get back to me. I had to contact him 3 times asking how far the procedure is and I was asked to get my own Settlement Statement from my current bank because their login is down. I got the statement and sent it to him on 22/10/18. I was told he will get back to me and it is almost the end of business of the 23rd and did not hear a single word from him. Seems like Hyundai does not want to do business with me. I will rather take my business elsewhere.
