Query: I am so SAD.

I love the original 3x3 Rubik's cube and I play with it all of the time. All of my friends had this 4x4 and it looked really fun. So I bought this 4x4 Rubik's cube and waited many days for it in the mail. Then I got the package, opened it up, started playing with it, and then 3 pieces snapped out and fell on the floor. One of those pieces was a center piece that can't be put back on. I wasn't even spinning the cube that hard, and it just broke. So right now I wasted 20 bucks on a broken piece of junk cube.
