That guy sells fakes, get your money back.
I am not sure where you found him, but his IG is sketchy. I don't think most of his posts are his photos. He sells TS for $750 and in his video showing them I can easily tell that they are fakes.
I found him on IG and I payed 750 for those shoes. I hope I get a refund. Thank you bro. I payed for a LC and they say me they were authentic. But looking myself to the photos I started to doubt about it.
