I received an item this morning from a seller (call them seller A). I was pleased with the item so left positive feedback. I've just got a message through the eBay message system from a different seller (seller B) saying that seller A sells fakes and uses several usernames. The message even gave seller A's contact details including phone number. They presumably got my ID off the feedback I left seller A earlier.
I little freaked out by this. Even more because I've already listed seller A's item myself earlier today.
What do I do? I've already emailed seller B asking what there evidence is but do I withdraw my listing?
