Hi, I am Steven Smith.
Hello, how could I help you?
 I made a reservation earlier to attend a get together party with my college friends. Due to some issues in college it  got postponed. Can you help me?
Sure, give me sometime to check and get back to you.
Ok.
Thank you for your time. Unfortunately we didn't found any reservation according to your name.
It's Ok, thanks for your response.
Thank you for picking us.
