How soon should you call a customer who has an ARMS reservation as a claimant?

The most appropriate guideline for contacting a customer who has an ARMS reservation is to aim for a call within 20 minutes, while ensuring that it does not exceed 2 hours. This response time aligns with best practices in customer service, where prompt communication can significantly enhance customer satisfaction and their overall experience.

Reaching out ideally within the 20-minute timeframe allows for timely interaction, which is crucial in confirming details relevant to the reservation and demonstrating attentiveness to the customer's needs. However, allowing up to 2 hours ensures that there is flexibility in case of unforeseen circumstances or delays. This balance of speed and tolerance helps in maintaining a professional standard of service and can potentially improve customer loyalty and trust in the company.

While other options suggest timeframes that may seem reasonable, they do not effectively capture the combination of urgency and flexibility that is inherent in option B.
