Missing or held up product in Prep Center. We submitted a prep form and listed a product on Amazon (both accepted). We had the product sent to the Prep Center, with indications that all were received and the status was listed at Accepted on Feb 10th. Since this time, we’ve received no status notifications of shipment or that it has been received by Amazon. We’ve emailed the Prep Center with no response and still no change in our product status. What possibly could have happened? and what else can we do?
