Frustrating

I am stuck on a day shift at my current job, when I actually want to be either in MY office sending out emails, phoning potential clients, or answering the phone to replies to our advertising. It is very frustrating not being able to quit this mind-numbing job and getting on with my REAL job.
I can't do anything here with people coming in and out of the control room all day long, and I have two more days of it! I have virtually nothing to do here, and I want to be busy in my office.
