Sold me a Prado with the incorrect specs

Morné and Gerrit sold me a Prado with a new but underpowered battery causing me to have endless issues getting stuck on the side of the road as a female on my own. When I eventually found out that the battery I had was not the correct spec for my car I called them up to discuss replacing with the correct battery. Their response - it’s not their problem as it’s after their 6 month warranty. So essentially they can sell you a car with incorrect parts but as long as you don’t notice within 6 months they get away with it. Check your vehicle thoroughly before buying from this company. I will definitely never use them again.
