Hi.
Hello, how may I help you today?
Jack Smith here.
OK.
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?
Sure, I can help you with that. Please wait.
Ok.
I regret that there is no reservation found on your name.
No worries, thank you for the information.
Ok, thanks for approaching us.
