This mob seem to be running some type of scam. They seem to be affiliated with 6pm.com, as we have tried to order from both sites, only to receive the same message from each of them. I'm not 100% sure how the scam works, but they want to get an "Approval" number so they can charge your bank account whenever they like. I had already confirmed with my bank that the transaction was legitimate, so there should have been no need for an "Approval" number. Shoes were never received, and support is very hard to contact, and slow to respond.
