How can i write a letter to administrator of hospital x-ray room door lock lock is not working properly?

Answer 1

To whom it may concern, (or if you kow the name of the person, write Mr/Mrs ....)

I would like to bring to your attention that the lock on the X-ray room door is not functioning properly, in the hope that you will have maintenance see to it as soon as possible.

Thank you in advance,

A concerned patient/employee (or your name if it's a private letter and not just a comment card...)
