I am not having a good experience with this dealer...

I am not having a good experience with this dealership! In fact that my vehicle still there and you know what? Its being over a week now. The service adviser promise to give us a quote for the tires last week and we were the ones who end up ordering the tires on tire rack. The service adviser also promise to give us a loaner vehicle Saturday and they didn't have one and we called Monday and they still didn't have one.... I am extremely disappointed and the service center of this dealership is nothing more than a mess!
