Hello.
Hello, how may I help you for this moment?
Owing an emergency, I want to cancel my reservation. Can you help me for that?
Sure, I will help you with this. May I know your name please?
Ok, my name is John Hill.
Please wait for a mean while.
Sure, I will wait.
Sorry Hill, there is no reservation found as per your name to cancel your reservation in your database.
That's ok, thank you for checking.
You are welcome.
