Renault sandero stepway clutch problem 46000km ????

Hi. I am very disappointed in the Renault Sandero Stepway I bought. I have driven several cars in past 20 years... and this car is the fist car that has a CLUTCH going at just over 45000km.... my previous car I did the clutch at 150000km and before that another car at 135000km ... I have spoken to the Renault franchise I bought the car from and they just say not covered un warranty... (wear and tear).. this is ridiculous because I believe this is a Renault problem.... every one I have spoken to several service garages including someone from the AA and they all say it should not happen on a new car that has just low mileage.... so now what. No one gives a ***** it is just your problem now. Would Renault please answer me. Leatitia ***
