Northcliff Nissan cost me R26 000

Northcliff Nissan made an offer on my car through Weelee. They outbid a few very good offers. We arranged an appointment after battling to get hold of Henry: the contact person. Not answering calls or whatsapps or emails. Took the vehicle in, nobody knew about me and Henry was not at work. After evaluating my vehicle they said they are not interested because of 2 minute paint spots. I fixed all the scartches through an insurance accredited panelbeater. I took the car back to the panelbeater and they fixed the problem. Emailed them back saying all is in order and were told they are not interested in my car at all. So why make an offer when you do not want my car ??? They offered me R271 600. Weelee said it is a bad idea to list my car again as people will think there is a problem. Because of them I lost R26 000 on my car as I had to trade it in. I am really unhappy and think they were extremely unprofessional. The service I received from Henry was terrible !!!!
