Theft off Cellphone

I have been in the maternity ward since the 03/02/2015, on the day of my discharge i went to the toilet from my bed when i returned to my bed my phone was missing, this is extremely disappointing due to this being a private hospital. What was distributing was that a male was allowed in my room unsupervised to hang curtains around the time my phone went missing!!! I could have been topless extracting milk! There was also a lady that was brought in across me which was still medicated and drowsy, anything could have been taken from her! The nurse said they usually dont leave people not from the ward unattended so why this time! The nurse also stated that a phone was ****** a week before so if this is the norm why are people left unsupervised! A maternity should be more secure than this surely as we have helpless babies in our wards, scary to think ********* work or easly can walk in to the maternity ward! I had a cesarean am i expected to ensure all my belongings are put away everytime i need to go to the toilet for a few mintues? Why do i use a private hospital! My baby is in neo natal, worrying about purchasing a new phone should be last of worries! Hope this will be taken seriously
