Missing items

I'm really upset with the service at bmw,I am the regular driver of my car,it was Makin some noise so my husband took the car in,he didn't check the car properly I had my volkano headphones, my airpods and my work usb in the car as I just arrived from gym..The day I needed to go in myself to collect the car after whatever needed to be done was done as I arrived back home I noticed that my stuff was no longer in the car,I confronted my husband and he clarified he didn't check although he signed a form to say he removed all the items from the car..please people if you guys go to BMW make sure all ur stuff is out Evan the ones you think are of no value,most of us feel that our things won't go missing as BMW is so reputable,please be weiry always..thanks
