There might have been a problem with your ID - it has to be an acceptable ID and it has to be an original ID and not a copy. Or there might have been a problem with your photo. For example, it might not have matched the photo on your ID.
We suggest that you try again with a different type of ID. If that doesn’t work, submit a support ticket. Here’s a link for contacting support: https://dealstream.com/help/writetous.
