Hi. Jason Baker is my name.
Hello, how may I serve you today?
My visit to the Auto-show event got cancelled, because of bad weather  conditions. So, for this I want to cancel my recent reservation.
Sure, we are glad to serve you.
Thank you.
Please wait for a while, let me check your reservation and revert to you.
Sure.
Thanks for your valuable time, sorry, unfortunately no reservation found with provided name.
Ok, no worries at all. Thank you for your helping hand.
Thank you for availing us, have a great day ahead.
