Me: “Hello, you’re through to the billing department. How can I help you?”

(All I hear from the customer is a high-pitched, incoherent screaming.)

Me: “Sir? Hello? I can’t understand what you are saying.”

(Still screaming.)

Me: “Sir, if you could just calm down and tell me the problem, I’m sure I can figure it out.”

(The customer keeps screaming. I hang up. Two minutes later, my colleague takes a call.)

Colleague: “Hello, you’re through to the billing department, how can I help you?”

(Incoherent screaming.)

Colleague: *looks at me* “It’s for you.”
