Storage King missing belongings

The delivery team was in such a hurry and rushed me because it was a Saturday and they needed to leave at 12. They stuffed My belongings into the units and I needed a 3rd unit to which they did have and initially said they didn't have a lock then 1 of the guys said he found a lock for the 3rd unit, on delivery day some of my items were missing, when I enquired they said no they have cameras and investigated there wasn't anything suspicious noted from collection or delivery. So where are my belongings??? They make you feel as if your lying and stole your own items. I will never recommend them to anyone or ever use them again
