Split casing

I have a 4gb fuze that I bought…Oh, Feburary of this year? Somewhere around there. Anyway, the casing between the charger/connect cord slot and the headphone jack, and the from the headphone jack up the side is split open on the join line. I haven’t done anything to it beyond normal use, and certainly nothing that should have put enough pressure on it to splt the seal like that, but I have no idea what to do about this, or who to contact, and was wondering if someone could shed some light on this for me.
