iPod and Stone

The girl of 14 years old to live in the State of Texas was given iPod from her father by birthday present. However, a stone entered not iPod when she opened it. Her father demanded returned goods, but the shop side is refused. He purchased iPod again unwillingly. However, the contents were stones again. He demand returned goods again. However, the shop side refused return of goods. And the shop side did not do the apology either. This is not forgiven. I think this incident is a problem in the shop side obviously. I think the shop wants to manage the article properly.
