Query: Waste of money! Many pieces of junk.

Purchased this toy because the picture on the box looked like it was a pop up airport. It's a piece of junk --- many pieces of junk which are difficult to assemble for a young child. The pieces keep falling off when you try to play with it which frustrates my five year old son. I wrote the company to complain and never heard back from them.
