Hello.
Hello. How may I aid you today?
Can you please help me by changing the existing reservation?
Sure, I will help you with booking, please hold on for a moment to check your reservation status. May I know your name please?
My previous reservation has done with the name Amy Allen.
Allen, I did not find any reservation with your name in my database.
Ok, not an issue. May be something went wrong while booking the ticket. Thank you for providing information.
It's my pleasure.
