Question

a customer who failed to fill out a refund application correctly is angry and wants to know why she did not receive her refund. it is best to say:
\you made a mistake filling out the refund form.\
\you did not fill out the refund form correctly.\
\the refund form was not filled out correctly.\
\the person who filled out the form did it incorrectly.\

Explanation:

To handle an angry customer, the response should be less accusatory. The first two options directly blame the customer ("you"), which can escalate anger. The fourth option is also accusatory by identifying the customer as "the person". The third option, "The refund form was not filled out correctly," focuses on the form's status rather than directly blaming the customer, making it the best choice for de - escalating the situation and providing the reason for the non - refund.

Answer:

C. "The refund form was not filled out correctly."
