Bad service

End of may we bought a car from motus select Alberton and the first instalment was on the 1st of July 2024 and on 9th Tuesday the car was leaking water so I called them and they say they will book it for the 10th Wednesday so I went there on 10th Wednesday left the car and they said they will diagnose it and see whats the problem and on 11th Thursday we went there with my wife and they told us they found water pump faulty so they have ordered a new pump so today the 12th I received a call from the salesman telling me that dealer principal refuses to pay for the water pump saying the car travelled 6000km
