The correct answer would be option C, avoid negative word-of-mouth from upset customers.
One of the reasons service failures need to be addressed quickly is to avoid negative word-of-mouth from upset customers.
Explanation:
When a company is unable or fail to deliver the expected service to the customers, this is called as the service failure. Service failure is usually temporary in nature and the customers are usually not compensated for that. But if the service failure is permanent, the customers are surely compensated for the inconvenience.
For example, if there is an internet service provider, and due to some problem, the service is temporarily not available, then this service failure must be addressed quickly to the customer, just to avoid the negative word of mouth from the upset customers.
