Please keep in mind that sometimes USPS does not update every step of the shipment progress even though the shipment is in transit and on its way to you.
In this case we recommend you to contact USPS directly, their phone number is 1-800-ASK-USPS® (1-800-275-8777). At the same time we will also open an investigation with them to track down the shipment.
Most likely your order will arrive within the next few days.
