Huge concern. Just had my tesla serviced at the Rancho Cucamonga Service Center. The center console sliding lid was replaced. After picking up the car, my wife drove my two kids home. After they got home, she realized that one of the car seats was not secured at all. The car seat was completely removed and unlatched from all three anchors. No one told her that the car seat was removed during the service. This is absolutely unacceptable. My son could have been seriously injured or killed if the car had gotten into an accident. How and who and where can I file a complaint?
