My car was taken in for an airbag replacement over...

My car was taken in for an airbag replacement over a month ago and I have been trying to get someone from Toyota Rockhapton to talk to me or even call me back in 5 minutes as they have said they would about my car and what is happening with it. Not only that Toyota Rockhapton get me a rental car that i am really happy about where they have said they will pay everything and i just put a $100 bond on the car which was okay. But now they dont even inform the rental company about what is going on with me still renting the car and now i am being charge rental price. I have been trying to contact Toyota Rockhapton for soooo long and trying to get them to call me back but no one does..... I am really p off about all of this.
