For some context about the video you're about to watch, we turn to Gawker:
After an unidentified security systems company missed an appointment, one inconvenienced customer phoned the company's customer service line to straighten things out.
Following a little back and forth, the issue was bumped up to a supervisor named Michelle, who subsequently phoned the customer and left him a message asking him to call her back to her direct extension.
And so he did.
Except that Michelle had apparently gone home for the day, and no one at customer service seemed to know her by name, so the customer was kicked around the system for over three hours.
He ultimately reached a tech support agent named Mark, and that's when he officially broke down and let the expletives fly.
Listen to the crazy call after the jump.
