 Hello, how may I oblige you today?

I am Frank White. I have reserved a ticket last week to reach my uncle's home but suddenly my trip got cancelled. So please help me with cancelling my reservation.
user
Sure, please wait for a while. I have checked in reservation list to cancel your ticket, but could not find any reservation with your name.
assistant
Oh! It may not be booked properly due to server issues while booking. Anyway, thank you for your time.
user
Your welcome.
