Hello.
Hello, how may I amend you today?
 I want to cancel my recent reservation, because I want to travel  with my friends by road. Can you help me?
Sure, we will help you. Can I have your good name to check your reservation?

Please wait for a while, I will check the reservation list and revert to you.
Ok.
