Once your order has been received by UPS or USPS, it is now the responsibility of the carrier to deliver your package. We are not responsible for carrier delays. If your package is lost, the shipping carriers have a 15 day waiting period to file a claim. As the buyer, you will be responsible to contact the carrier directly to file a claim. You will need a copy of the invoice you received when your order was placed and the tracking number we provided when your order was shipped.
