Angry without sleep

Was up until 6 am working on an issue in a customer’s maintenance window. My whole day’s been messed up as a result. These guys are the biggest bunch of amateurs I’ve seen; after repeatedly giving them my cell phone number, none of them called me when their server started acting up. A handful of customers saw an unusual dialogue box, and started calling in. So these guys call the president of my company and start freaking on him.
Me, I heard none of this, despite still sitting in front of my computer, with my cell phone and pager on my desk in front of me. By the time I got into work at 9am, everything’s going crazy and they ended up unsetting a single option which they had earlier told me to set. Bunch of fucking amateurs.
