Final answer:
Statement C, 'Escalation requester can only escalate cases,' is likely incorrect as it narrowly defines the role of the escalation requester, who may have other responsibilities besides escalating cases.
Step-by-step explanation:
When considering which statement is incorrect regarding case escalations in customer service, we must understand the roles and common practices within the context of business operations. The statement A. Customer service agents manage case escalations is typically true, as customer service agents often handle initial queries and may also be responsible for managing escalations if the case requires a higher level of attention. However, the statement C. Escalation requester can only escalate cases might not be accurate, as 'escalation requesters' could also be involved in other tasks besides escalating cases. Case escalations are not the sole function of any individual in customer service; team members may have additional responsibilities or functions. Thus, statement C is likely to be incorrect in the context of being solely able to escalate cases.
