Not A Sound Reason For Calling

Me: “Hello! You’ve reached [company] tech support. What can I help you with today?”

Caller: “Yeah, my phone doesn’t make any sounds. It vibrates when someone calls, but it doesn’t ring or anything.”

Me: “Hmm… that is kind of strange. I know this is going to sound really obvious, and I apologize for that, but have you tried pressing the volume buttons on the side of the phone?”

Caller: “Yeah, I’ve done that but it doesn’t do anything. Here, I’ll show you…”

(I hear the sound of his phone beeping.)

Caller: “SON OF A B****!”
