Hello.
Hello, how may I serve you?
I am Shirley Baker. I made a reservation earlier to attend a get together party with my college friends. Due to some issues in college it  got postponed. Please help me in changing?
Sure, we will help you in changing. Let me check your details in our database and I will revert to you soon.
Ok.
Sorry to inform you that there is no reservation found on your name to proceed further.
Ok, no issues.
Thank you for contacting us.
