Remo Motors Misrepresentation and high interest charge

I bought a Nissan X-trial in September 2020 from them. I asked if the vehicle was in an accident and they advised that it was not. On top of that I was charged the most ridiculous interest rate when my credit record was great, they took advantage that this was my first car. Fast forward a year later I find out while they vehicle was in for repairs that the left fender does not have the same color as the rest of the vehicle, indicative of repairs on the vehicle. So the vehicle was in an accident afterall! These guys are one of the reason the used vehicle industry in South Africa is a scam!
