As my uncle's house warming ceremony  was postponed. Would it be possible to change my existing reservation?

Give me a minute I will check your reservation.
assistant
Sure.
user
Sorry there is no reservation found on your name so it's not possible to change an existing reservation.
assistant
No issues, thank you for the information.
