Audi Q3 TDI breakdown 25000km

My brand new Audi Q3 2015 lost a cambelt on 25000km unexpected for so low km. The service department has not called me once to inform me of the status of my vehicle, I have to do all the follow ups. Currently I am sitting without a vehicle no curticy car, no-one calling me from the service department to inform me of the damage/ expected duration on the repair of the vehicle. No one doing any effort in keeping the customers informed. I am currently lost as an Audi fan, I will move to another fabricate as soon as the repair is completed. Totally waste of money to buy an Audi.
