Hello,. I am Katherine Carter.
Hello, how may I oblige you today?
Actually I made a earlier reservation to go for a trip with my friends, but heavy work load in office I want to change my reservation. Can you help me with that?
Sure, we are here to help you.
Thank you.
 Please wait for some time, I will check with your reservation status and revert to you.
Sure.
We hardly tried to find your reservation but, no reservation has been found with your name.
Ok, no issues. Thanks for the information.
