What is a suitable course of action if a customer wishes to extend their rental period?

When a customer wishes to extend their rental period, the most appropriate course of action is to request an extension from customer service. This option allows the customer to directly manage their existing rental agreement without complicating the process. Customer service representatives are equipped to quickly check the availability of the vehicle for the requested extension duration, inform the customer of any additional fees, and ensure that the rental agreement reflects the new timeline.

This process is generally smoother than making a new reservation, which could involve additional steps such as cancellation of the current rental and potentially losing the current vehicle. Meanwhile, contacting the main office might not be necessary since customer service is typically able to handle these situations directly. Lastly, returning the vehicle early is not a suitable action if the intent is to extend the rental period; it contradicts the customer’s request. Therefore, requesting an extension from customer service is the most effective and efficient solution.
