I LOST IT!!!

The DM's walkie-talkie cum hp that is...Realised the loss when I wanted to walkie my Security Officer...called the number, but alas, it automatically led to the voicemail.
Two possibilities: the phone was switched off or the phone is in an area where there is no reception.
Backtracked, but still could not locate it. Searched the back office but negative findings.
Im prepared to pay for the phone but that's not the main issue. Not nice lah, to leave on a note like that...what a night!
I still have to run the shift...
