Query: keeps falling down!

My daughter had this for christmas, after nearly an hour removing all the ties, threads, tabs and tape, adding all the stickers and several attempts to get all the columns and stairs attached at the same time my little girl finally got to play with it! It has since fallen down a least 3 times as the columns don't lock in place and it wobbles when you put any of the dolls on the top level. Overall I was very dissapointed by the quality of this toy and will be writing to Mattell to complain.
