Query: Disapointed

I bought this Barbie for my niece's Easter present. I put the first extension in wrong and there went the fun. She calls me about once a week to ask me to buy her more hair. I can't find it anywhere! Don't think about calling Mattel to order it either. They send you back to the store. I wish I had gone with the SpongeBob Barbie instead....
