Tom: I'm calling to make a complaint about the SMART backpack I ordered from you last week. I got it this morning, and it’s smaller than the one you advertised online.
Trang: Well ... Let me check it.
Tom: And I’m not happy with the colour, either. In your picture it’s dark brown, and this one is yellowish brown.
Trang: I'm sorry about that. I'll send you another one.
