Final answer:
Word-of-mouth communication about a service can be both verbal and nonverbal. False.
Step-by-step explanation:
The statement that word-of-mouth communication about a service may be either personal or non personal, but it is always verbal is false.
Word-of-mouth communication is a form of communication where information about a product or service is spread by individuals through conversations with others. While verbal communication is the most common form of word-of-mouth communication, it can also be nonverbal, such as through gestures, facial expressions, or written reviews.
Therefore, the correct answer to the statement is false.
