SAU worst customer service

After I finally could collect my vehicle, (more than a month later to repair a broken window - and never a phone call or an update) I discover that the broken door mechanism was not fixed so the passenger door still does not lock. Your supplier (Advance Auto Body) explained that they were not contracted to fix the door. Can you please let me know how to proceed, I prefer to have it fixed and send you the bill as I have lost all patience and refuse to be without a car for another month. The missing beading on the roof was also not replaced - Advanced Auto Body said "Ja, you can buy that from Toyota - why have insurance then??) So - I was without a vehicle for more than a month to discover only one item was fixed? Really?

At this point I feel I should expose the bad service I received - I have never had such pathetic customer service in my entire life. "Place your trust in excellence, place your trust in SAU". I think not!
