horrible service at audi centurion and no communication

i bought an s3 from audi centurion my 1st week of driving it the car engine light went on and car stopped, called audi to tow the vehicle they took 3 hours to get to me - car on motor plan 2015 model. this is the 3rd week im still waiting for my car. i think audi centurion service is absolutely disgusting and they got a bunch of silly employees. the service provider cannot communicate properly,still did not receive a spare keys or my service book. dont know what to do. think i will get the ombudsman involved now.
