Faulty Air-condition and 'Audi does not promise mobility to its customers'

Most ****py customer service ever,even after eascalating the matter to the supposed manager. We are now stuck with an air-conditionedless car for the weekend mainly because they can't diagnosis our car today,they don't have courtesy cars and they have customers whose cars are immobile meaning they would rather offer their courtesy cars to the immobile customers than us with 'driveable' cars. It's not the first time we experience such service from Audi,pity we liked our one year and a half SQ5 but eventually will have to change this *********** company with lousy customer service. The manager had an audacity to say Audi does not promise mobility to its customers, I take it they promise immobility and faulty parts as we have experienced.
