I am very angry, this product is false advertising. Piece 1 and 2 do not fit with the structure at all, I need my money back, I will not pay the return cost. I spent 3 hours trying to figure out what I did wrong and finally concluded that the structure itself is poorly made. I read the product comments and I found that the same thing has happened to more than 1 person. Then I try to report the problem to the supplier and it wont let me send the report!
