Falsely advertising vehicle as a later model and refuse to give my deposit back.

I paid a deposit of R4000 to bid on a vehicle on WeBuyCars and bid on what was advertised as a 2008 grey Land Rover. I got a sales agreement that said black but I dis-regarded it as the dekra report matched the advert. Then I noticed that the illegible diagnostic report showed 2007 which was the only thing legible. I looked at the disc pic no disc. I then contacted land rover directly to find that it is a 2007 model and was registered in 2007 and is not a 2008 as I was lead to believe. This is a gold sticker dekra report that WeBuyCars provided and the comments on the report refer to the attached illegible diagnostic report and pictures (blank disc)also stating that it comes with a roadworthy voucher. I have proof of another vehicle I was considering buying prior to this last week and when compared the exact same thing they declare the car as a newer model than it actually is and the disc also not displayed on the dekra report. The vehicle apparently has no issues. I contacted WeBuyCars to tell them that I bid on a 2008 model and that I want the R4000 refunded because that is not a 2008 model as advertised, so it is false advertising and also falsely written on the dekra report as well however diagnostics and Land Rover itself confirms the model. It also shows with Land Rover that the vehicle was first registered in 2007. I specifically chose the car for the newer model. I was told to hold on they would put me to the correct department, after holding for 26 minutes I got put through to the Richmond branch to the same sales consultant Raees in Richmond who was trying to assist me to close the sale. I told him that it was falsely advertised and I bid on a 2008 model grey not a 2007 model and that the reports don’t match and I do not want to continue because that’s not what they are giving me, and also not whats on the sales agreement I downloaded (which thankfully I have not signed). He was polite a have no complaint against him, He went to a manager to enquire and then returned to the call and told me that his manager said straight up that I won’t get my deposit back. That’s standard auction rules, I told him that the auction also has a responsibility to advertise the correct product to the consumer. We buy cars are falsely advertising their vehicles as newer models to what they actually are which will naturally attract a higher purchase prices. I want my deposit back! I had every intention to purchase the vehicle if it was what I bid for but now I have two reports of two different vehicles with the same issue that shows me it is deliberately and knowingly done to deceive consumers. I thought if I had brought this problem to their attention they would refund me and I still intended on purchasing a vehicle from them, but one which I could see and verify the details matched, however after this ***** behaviour and reports and then the arrogance of the manager at Richmond branch it’s made me reconsider- I don’t want to do business with these people at all anymore, I just want my money back because I bid on what was advertised falsely. Whilst writing this the manager alridge called me to tell me that he has a natis report to say it’s a 2008. But that contradicts how it could be a 2008 model and registered in 2007? I bid a higher price for a newer model, I would bid lower or not at all for an older model. Also I do not have the diagnostic report and the dekra report says “During the diagnostic no active error messages were detected. (See also attached Diagnostic Report. For more information regarding the Fault Codes (DTC) and the recommended rectifications please contact the workshops of the vehicle manufactures).” at the bottom I can vaguely see dtc1 but I have no way of knowing what that error is as nothing is legible. I was ready to pay for the vehicle but now I’m very dissatisfied with all this. I want my money back.
