Broken

After my dog was using this door for several months he somehow pulled the outer flap out of the groove. The construction of the unit is made in a way that once it has been put together,/glued there is absolutely no way of sliding the flap's aluminum top's groove back into the plastic body since the outer cover is glued and sealed against both ends. After hours of trying to pry the flap back into the groove it became apparent I would either destroy the plastic body or have to give up and live with the single flap. But with one flap the wind consistently blows it open sightly letting cold air into the house killing my heating bill. When working this was great but without an outer flap it is useless and a complete waste of $100 because of a horrible design flaw preventing you from being able to reattach the flap if it happens to get knocked out of it's groove.
