I recently got a thank you and a refund for towels I had returned from Amazon.

The towels were damp from bring used, I had never initiated a refund return, nor had I in fact returned them.

I reported this to amazon and had to find a human since the system had no "refund for nonexistent returns" option. The human didn't get it and pinged his team lead. After 20 minutes they told me to just keep my towels and refund.
