Hello.
Hello, how may I help you?
Can you please help me in changing my recent reservation? As my planned trip has been postponed to some other trips.
Sure, I will help you.
Ok.
Can I know your name please?
Yes, my name is Steven Brown.
Please wait for a while.
Sure, I'll wait.
Sorry Steven, there is no active reservation found with your name in our records.
That's ok, thank you for giving the information.
Most welcome.
