'I arrived at 7:30pm. The check in office is close . I called the phone number, but no one answered. I asked some tenant on the site. They said I can scan the QR code to check in, but My conformation number didnt work. I just don’t understand why the conformation number didn’t work. Other tenant said hers not working too. No one can help if conformation number doesn’t work.'
