exorr -- I'm sure the mods will lock this pretty quick, so here's an answer before they do.
Call SVCompucycle to see if they have a tracking number. If the USPS says they delivered it, they may have it, too. In any case, ask where they delivered the package.
If it was not delivered to your address, the dealer owes you a replacement, and the loss is between them and the USPS. If USPS shows the package delivered to your address, and it was stolen, it is a Federal offense, and you should be able to get some help from them.
Good luck.
