Hi,.
Hello, how may I assist you?
Can you please help me out in changing my existing reservation? As my planned trip has been postponed to some other dates. Can you please help me?
Sure, I am here to help you. Can I know your name to check your details?
My name is Jessica Brown.
Sorry to say, no reservation found on your name.
That's ok, not an issue. Thanks for your response.
Thank you for reaching us, have a nice day.
