Hi.
user
Hello, how can I guide you for today?
assistant
Owing to an emergency, my planned trip to Yosemite adventure got postponed. So I request you to alter my existing reservation.
user
I am here to help you with that. Could you please provide your name to check the active reservation?
assistant
Sure, I have a existing reservation with name Amanda Brown.
user
I regret to say this, I have not found any active reservation with such a name to alter your reservation.
assistant
Ok, no worries at all. I appreciate your kind service.
user
You are welcome, thank you for reaching our service.
