Which of the following is NOT a step in handling a valid complaint?

Blaming the customer for the issue is not a step in handling a valid complaint, as it undermines the purpose of effective customer service. When dealing with complaints, it is essential to take accountability and acknowledge the customer's feelings and experiences. An effective complaint resolution process involves showing empathy, apologizing for the inconvenience, and ensuring the customer feels heard and valued.

The other options reflect best practices in complaint handling. Apologizing to the customer conveys empathy and acknowledgment of their frustration. Stating how the situation will be handled reassures the customer that their issue is being taken seriously and that there is a plan in place to resolve it. Following through and following up helps to ensure that the resolution meets the customer's needs and reinforces a positive relationship going forward.
