Cell phone ****** out of closed change room

My husband and child went to the above store to buy something for her to wear to youth.<br> My child gathered some clothes to try. Went into the change rooms, clothes and cell phone in hand. Chose a change room close to the door. She put on some garments, left her clothes, the excess store clothes - CLOSED the change room door! and walked 8 steps out of the change room to show her father what she had on.<br> When she started trying on the next item of clothing, she looked through the clothing and found her cell phone S4 Samsung was gone. Being 14 she panicked, raced out the change room and told her father what had happened. Immediately the gentleman speaking to my husband rushed to the front door, asked the security guard not to let anyone out, they apparently looked at him blankly, like he was speaking a foreign language. He called the manager, while my child and husband never left the change room. THE ONLY OTHER PERSON THERE, was the attendant. When asked where the cell phone was, she also shrugged and said she didn't know!. And low and behold, the store manager had just left the building!..... the disinterest was astounding and the phone was instantly switched off.
