Hello.
Hello, how may I serve you?
As my manager did not approve my leave, I would like to change my recent reservation. Can you aid me with this?
Sure, I will help you. Please provide the name on which ticket has been booked previously.
The ticket has been booked on the name of Emma Anderson.
Sorry, there is no active reservation found in our database on your given name.
