Hello.
Hello, how may I help you?
Can you please help me to change the travel dates in the past reservation?
 To proceed further, can I have your name please?
My name is Jennifer Johnson.
Thank you. Please be online for a while. I will check your reservation status and get back to you.
Ok, take your time.
I am sorry to say you that there is no reservation found under your name in our database.
It's ok, not a problem with that. Thank you for your time.
Welcome Jennifer Johnson.
