Who should be contacted for inquiries regarding a consolidated callback?

The Rental Management Center is the appropriate contact for inquiries regarding a consolidated callback because this center typically handles operations related to vehicle rentals, including coordinating maintenance and repair issues that arise with rental vehicles. When a consolidated callback occurs, it often relates to a broader issue affecting multiple vehicles within the rental fleet. The Rental Management Center would have the necessary resources and expertise to address any concerns about the rented vehicles and facilitate communication between relevant parties.

In contrast, the other options do not align with the nature of a consolidated callback. The Corporate Business Center usually handles corporate-level inquiries and may not specialize in specific rental vehicle issues. The insurance company would deal with claims and policies rather than vehicle maintenance, and the local repair shop would focus on performing repairs but would not have the broader context needed for a consolidated callback scenario.
