Hello. Jonathan Parker here.
Hello Parker, how may I assist you today?
I want to change my previous reservation because I made my booking with wrong travelling dates.
Ok, please wait for a while, I will check the status of your reservation.
Sure, take your own time.
Sorry, there is no reservation found with your name in our records.
It's ok. Anyway, thank you for your help.
