Hi.
Hello.
I am Donald Allen.
How can I help you?
Can you help me for cancelling my recent reservation, because I am unable to travel at this moment?
Sure, please wait for a while to check your reservation status.
Ok, I will wait for your reply.
Sorry, there is no reservation found by your name.
Oh! It's ok, no problem thank you for your services.
Thank you and have a nice day.
