Hi.
Hello. How can I aid you?
Please cancel my recent reservation. As budget was very high for our planned trip and we are not able to  arrange our budget, so can you help me with this?
May I know your good name?
My name is Charles Lewis.
 Ok, please wait I will you know.
Ok.
 Sorry, no reservation was found on your name.
No issue, thank you.
 Thank you.
