Hello, Mary Taylor here.
Hello, how can I help you?
I made a reservation before, but now I am unable to travel to that. So, can you help me in changing my reservation?
Sure, I will help you.
Thank you.
Please, standby.
Sure, I will wait.
Thanks for waiting, I am sorry to inform you that, there is no reservation found on your name.
That's ok, I think my friend has approached another agency for booking the ticket. Anyway, thanks for your effort.
Thank you for reaching us.
