Hi. I am Debra Thomas.
Hello, how may I serve you today?
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, we are here to help you.
Thank you.
Please hold a moment, let me check your reservation and let you know.
Ok, take your own time.
Thank you for your valuable time, unfortunately no reservation found with provided name.
That's ok, thank you for the response.
Thank you for availing us.
