Sorry for all the frustration you've experienced so far, all the information you need on how to create and manage a Spotify Artist page should be located here.
Do you have your music on Spotify already? If not, please have a look at the 'How do I get my music on Spotify?' tab, and if you do, the 'How can I manage my artist profile on Spotify' tab should be the one you're looking for.
Please reply if there's anything else I can help you with!
