Which of the following is a valid option for submitting service concerns?

The correct choice is valid because it encompasses multiple established channels designed specifically for submitting service concerns. These platforms—FACTS, UNITED VOICES, BLOCK2BLOCK, and SERVICE FEEDBACK—are institutionalized methods that ensure service issues are documented, tracked, and addressed by the relevant departments effectively. They are structured to facilitate comprehensive reporting and feedback, making them reliable choices for voicing service-related concerns.

While other options like manual submission, direct email to management, and a pilot feedback form may exist as informal ways to report problems, they do not necessarily follow the standardized protocols that the chosen option provides. The formalized process outlined in option B not only aims to gather feedback efficiently but also ensures accountability and enhances the potential for improved service delivery over time.
