I have not read all of the posts in this thread, but I am sorry for the OP’s troubles with this seller.
We’ve discussed extensively why we don’t do store rating on these forums, someone please link the explanation whenever the topic is brought up.
I’m glad you reported it to an FBI. Beyond our ratings system when that it is applicable, that is what we recommend.
We are open to receiving feedback about sellers on our site for situations that took place off site, however these will generally go into our private notes and factor into judgments in future situations with those sellers rather than being a case that we will act immediately on. It is a lot of work to investigate these kinds of situations especially to the point of making a severe judgment on a seller. We have seller who are causing problems on our site and our energy is focused there. In the coming months we will be producing better document policies on this kind of thing. So please do report it but with tempered expectations.
