Reservation question

[DisneyKhormid]

I've been making reservations, changing them and cancelling over the last week or so as we iron out our plans. I'm not receiving cancellation emails except on two occasions but they do show removed from disney experience. Should I be concerned that I don't have a cancellation email? I don't in an event of an error to be charged for a reservation I've cancelled and not have proof. Thanks for the help
