Hi.
Hello, how may I address you?
I am Andrew Green. As there is a change in trip, I would like to change my existing reservation. Will you help me in this?
Sure, I will help you.
Thank you.
Please wait for a while, I will get back to you with current status.
Sure.
Thanks for waiting but I am sorry to inform that there is no reservation found with your name.
Ok, thanks for the quick response.
Thanks for reaching us.
