Hi.
Hello, may I know your name please?
I have to change my existing reservation, because my nephew's marriage was postponed. So, can you check it?
Ok, I can help you.
Thank you.
Please provide your name?
I am Donald Gonzalez.
I have checked for your reservation but, I got to know that you have no reservation done with us.
Ok. Thank you for the quick response.
Thanks for contacting us.
