This is most probably due to the fact that you failed to confirm your e-mail address within the first seven days after registering. When you create your hvv switch account, you’ll automatically receive a registration confirmation e-mail, sent to your personal e-mail inbox. This e-mail will contain a link that you can click to confirm your e-mail address. We want to make sure that you really are the owner of this e-mail address and that important information and invoices can be sent to you securely. If you haven’t received the e-mail, you can request that a new confirmation e-mail be sent in your account/profile.
