Hi.
Hello, how may I aid you?
I want to make some changes in my reservation, could you please help me with that?
Sure, I am here to help you out. Please provide me your name to check with your reservation details.
Sure, my name is Cynthia Phillips.
Sorry, I can't help you in modifying the reservation because I didn't find any reservation on your name.
Oh! That's fine, thank you for checking.
Thank you for reaching us.
