Reall bad servivce from "service" managers

Really bad service from service advisor (Edierioes) and the manager (Mumtaz) After having headlight issues from the time I purchjased my car, I finally demanded that they check the headlights rather than just replace the bulb. Getting Ederies or Mumtaz to respond is a nightmare! They just ignore your messages and emails. They have promised the car willbe fixed under warranty and they will supply a courtesy vehicle. Now they just ignore me.... I am beyond frustrated!
