Which of the following is NOT a reason for a chargeback?

The correct choice indicates that "Vehicle delayed return" is not a recognized reason for a chargeback. Chargebacks typically arise when there is an issue directly related to the transaction that justifies a customer disputing a charge with their bank or credit card provider.

In the context of chargebacks, the reasons listed generally involve clear, transactional discrepancies. For instance, "No swipe or imprint" is a procedural failure that indicates the transaction was not properly authorized, while "No signed rental agreement" highlights a lack of documented consent for the terms of the transaction. "Charging a card more than 30 days after contract closes" also relates to a breach of agreed-upon terms and can trigger a chargeback due to the timing of the charge.

Conversely, a vehicle's delayed return does not usually pertain to the core transactional issues that establish grounds for a chargeback. It typically falls under operational or service-related problems within the rental agreement, rather than a failing in the processing of the payment itself. This distinction helps clarify why vehicle return issues are less likely to be associated with chargebacks compared to the other provided options.
