AUDI South Africa

I have been having issues with lights and car stalling etc. and booked the car in. This morning my car did not want to start and battery issues..... Audi advises they do not have courtesy cars to provide whilst they fix THEIR FAULTS and put owners and live IN DANGER - is it worth the premium price you pay for the AUDI BRAND ??? AUDI A3 SEDAN 2015 RECALLS.....due to technical issues with these cars ??????
