(I call the customer.)

Customer: “Hello?”

Me: “Hello, this is [me], may I please speak to [customer]?”

Customer: “Yes, speaking.”

Me: “I am calling from [company name]. There is a slight issue with your account. Do you have a moment to discuss this issue now?”

*long pause*

Customer: “Hello? Hello?! Sorry, I have terrible reception here.”

Me: “Sir, I am speaking to you on your home phone.”

Customer: “What?!” *hangs up*
