Call Transcript (04.02.2024)

Thank you for calling Acme Corporation, Sarah speaking. How may I assist you today? Hi Sarah, this is John. I’m having trouble with my Acme Widget. It seems to be malfunctioning. I’m sorry to hear that, John. Let’s get that sorted out for you. Could you please provide me with the serial number of your widget? Thank you, John. Now, could you describe the issue you’re experiencing with your widget? Well, it’s not turning on at all, even though I’ve replaced the batteries.

The customer, John, called Acme Corporation's customer service department to report a malfunction with his widget. Sarah, the representative, attempted troubleshooting but concluded that the widget needed repair under warranty. She offered to send a prepaid shipping label for the return of the widget.
