Worst Customer service experience Renault Motus Zambezi

Hi there this is how Renault Motus zambezi have been acting towards their clients , on the 10/03/2025 our Vehilce Renault Duster 2018 went in for Major Service with timming belt on the 9/04/2025 the car broke down it was taken to Renault Motus the service advisor Elias informed us that its The Tenioner that Failed , then the Manager cane from leave and informed us that is the keyway key that broke and that's the cause the valves bent and amongst other things , I want to make it clear Renault Motus Zambezi did not assist us with Curtesy vehicle or anything else they told us to get a cheap engine that would be a better option , no Customer Relations nothing , the vehicle has a full service record they did the 180km service on the Vehicle there was no issues regarding the Timming belt or tenioner that was changed by them only afterwards this occurred
