This is how Amazon handles refunds for late deliveries.
Merchant fulfilled: You should have used a better carrier! We will deduct the funds from your selling account
Amazon-fulfilled: The carrier we used was slow. We will deduct the funds from your selling account.
Funny how there are only 3 major carriers in the US to use, and we all use the same ones, but when Amazon uses them it is still your fault for not.. flying it in your personal helicopter?
Another aside, we had to stop fulfilling orders to people in the service. Believe it or not, accurate delivery scans for tracking API's aren't a priority for the military, especially in overseas bases. Could even be a security issue. Well, Amazon was going to punish us for these orders not showing final delivery, despite no customer complaints. So we had to stop sending headphones, protein powder, all sorts of stuff to our military members because Amazon cannot see the forest through the trees.
Every so often we get a product taken down until we upload paperwork from the manufacturer. But if one customer doesn't know how to connect to widgets together and complaints that it must be fake, Amazon suspends our listing because it must be counterfeit - even though it is our product AND we gave them the damn documentation previously. Losing thousands of dollars, have to cut hours for employees because Amazon support in bongobongostan cannot read.
I welcome Amazon getting spanked.
