Hi.
Hello. How may I help you?
I want to change my existing reservation which is done recently due to some problems, can you please help me in this?
Sure. Tell me your name please?

Please wait.

Thanks for waiting. But I am sorry to say that there is no flight reservation on your name to change it.
Ok, no problem.
Thank you.
