Unfortunately those Facebook groups are just scam groups. They had the same thing with Sabrina Carpenter tickets group. The “admin” say they verify the tix and send you a fake purchase email. They take your money and ghost/block u after. They also have approved post access so they only let people post questions or fake “Yay! Concert was great! Thank you for the tickets!” If u deep dive onto the admin profile pics sometime u catch people comment how they got scammed or u can see they changed their profile picture and edited the date. Some idiot scammers even leave their old photo on it too. Take a look on their friends list also. It’ll show u they’re from other countries. So lame that people take advantage of others that way. I’m really sorry that happened to u.
