Answer:
Understanding the caller and Knowledge of the product or service
Step-by-step explanation:
The 'knowledge of the product or service' element of customer service of what is done by whom and the understanding of what the customer or caller is looking for must be improved also. Here, Bonnie calls the hospital and the operator carefully listens to what she has to say. Bonnie has a problem with her bill rather than a medical issue and this aspect is important. The operator must have asked a question trying to understand the problem and then should have used his knowledge to direct her to the billing department directly as bills are handled by the billing department. The understanding of the problem and knowledge of the institution needs to be improved.
