Amazon doesn't distinguish between a package being lost, and being delayed, apparently. My 2nd order is delayed with no explanation, and I expect another message saying "maybe we lost it". I went on chat regarding the issue, and the rep said I have as much info as he does.
Amazing that Amazon ships millions of things per day and doesn't distinguish between something delayed, and something lost. I told the rep where I was going with my line of questioning, that every time I get a message saying the item "might be lost", I'm going to order another one, and that I'm only expecting and accepting 1 item to be delivered. Delays are understandable, not knowing the difference between a lost item and a delay for a company that size is incredible.
I picture myself as a package delivery person walking up to an address empty handed, greeting the resident, and telling them I can't explain why my hands are empty. "I've either lost the package, or it's very delayed for unknown reasons", I tell them.
