Query: hard to put together- wheels wouldn't stay on

I bought this a while ago for my son. It took me a long time to put together and I had put together a crib, swing, highchair, etc. all by myself so it's not like I am incapable of following instructions. The wheels wouldn't stay on mine because I snapped a piece off when putting it together lol. So we used it wheelless for about nine months- it was nice storage place even though I couldn't get the shelves to lay completely straight. I ended up just throwing it away.
