Complain

I have sent my car for a service on the 23 of September. when went to fetch the car some of my items were ****** from the car when I spoke to the manager he told me that he will look into it, It been a week since my interaction with him. I was told that the car was sent to the car wash, that where my GPS was ******, the funny part I did not send my car to the car wash I sent it to ford. ford must liability for my missing GPS. The car washes its third party to them.
