Hi, I am Amanda Phillips.
Hello, how can I serve you?
I want to do some changes in the existing reservation because my friends are not able to come on those dates, can you help me in changing an existing reservation?
Sure, give me sometime to check and revert to you.
Ok.
Thank you for waiting. Unfortunately we didn't found any reservation according to your name.
Ok, not an issue. Thank you.
Thank you for opting us.
