I think CN feedback goes right to /dev/null so there is no point in sending them any issues. I know I never recieved any responces on the few I sent over the years.
as for your issue, it is relitivly common for occational loss of items.
the only way to get the stuff back is to find the minigame that these came from. It will have the presents back in the HighScore list, so replay that level.
typically it is not the eniter minigame so check each levels High score before replaying them.
I have 4 Friends at BFAHP and I lost some items only a few times.
