Hello, myself Shirley Harris.
Hello, how can I assist you?
I want to do some changes in my existing reservation because I did not get the concert tickets, so planning to travel on another date, can you please help me?
Sure, just be on hold, I will revert you.
Ok.
Thank you for waiting, I have not found any reservation by your name.
No issues, thank you for providing information.
