Hello.
Hello, how may I guide you?
 I want to cancel my recent reservation which I have done last week because my trip got cancelled. Please help me out with that.
Sure, please provide your name.
My name is Charles Adams.
Ok, please wait a minute.
Ok, take your time.
Sorry Charles, there is no active reservation found under your name in our records.
It's ok, thank you for your help.
Most welcome.
