Talk to a local lawyer.
Even if you're not obligated by law to do something about it, that doesn't mean that you can't be nice. How would you like someone to react if you send your stuff to the wrong address? If this were unsolicited, I would definitely talk to ST and tell them I can send it back (or they can send someone to pick it up) at their expenses. I would refuse to pay the invoice, however, if I didn't order it.
