Undisclosed information from Salesmen

My husband bought a second hand Suzuki dzire 2024 in January 2025 on 43 000km and was informed by the salesman (Mfundo Williams) that the service warranty/service plan ends at 45000km. We then drove the car for only 2000km and when we tried to take the car for service we were told that service warranty ended at 30 000km and therefore we should now pay for service from our own pockets. Imagine buying a car and driving it for only 2000km then have to pay from your pocket cos we were not gonna take that car if the truth had been disclosed to us. This is really unfair, even worse, finding out on the day when you have already booked the car for a service. We were going to but about 2 more cars from this garage cos we use them for business but now we have to look elsewhere. Very disappointing!
