I was scheduled for a sleep study over two weeks ago. I told the staff three times that I worked swings but when I got there the tech knew nothing about it so they sent me home and rescheduled me for a Saturday. When confirming my appointment the secretary told me to be there at 8pm no one was there to check us in etc. I had to go all the way to the ER to register and sat around for an hour before someone showed up at the sleep lab.
