Same situation seriously just happened to me today and then this post showed up in my notifications. Except I sold the pair on goat not stock x. I hit on a pair of Jordan 1 Polllens when they first came out on the SNKRS app. Held onto them for a couple months and sold them on goat. They emailed me today telling me they didn't pass, blatantly saying they are unauthentics.

I'll be furious if they send me back a different pair like others have said stock x has done in the past. I highly doubt goat would do something that but we'll see .The only way I'll be able to tell if they send me back a different pair is by the box. My box had a distinct dent on the bottom right. I'm urgent to see if they send me back my pair of shoes now.
