Me: "Hello, this is [Company Name]."
Caller: "Hi, who just called me?"
Me: "I’m not sure. You’ve reached general reception."
Caller: "Well, someone just called me from this number."
Me: "Sorry, but there’s no way for me to tell who called you, as this is the general number."
Customer: "What are you?"
(I explain the company.)
Customer: "I didn’t understand anything about what you just said. Why did you call me?"
Me: "It could be a wrong number."
Customer: "Ugh, fine. Stop wasting my time by calling me if you don’t know who you are, please!"
