Hi all! I'm looking at the tracking information for my book and it's showing a very strange history. It appears my book was sent out, made it all the way across the country, got put on a US Mail truck for delivery, but it never got delivered. After, it seems to have "bounced" back to Cali and now, the tracking seems to suggest it's stuck in some sort of limbo. Which is to say there are no updates to tracking for three weeks now. Who can I speak to in order to look into this?
