Hi. I am George Garcia.
Hello, how may I oblige you for the day?
I would like to change my existing reservation due to some health issues. Can you be my helping hand in this?
Sure, I will check your reservation in the list and get back to you.
Ok, I will wait.
Sorry, we couldn't find any reservation on your name.
That's ok, not a problem. Thank you for your information.
Thank you for contacting us.
