Trouble to set up website

I am trying to reset my website [login to view URL] that was taken down. My hosting is 3ix. I have to start over and upload all content again. Now, I have been in a live chat with 3ix and they will help me get my website up and running again with a new theme. I have purchased the domain, theme and paid off my debt to hosting. Everything should be ready to go. They are asking me to upload my purchased theme to wordpress. To log in I should go to [login to view URL] and I have the username + password to log on BUT I am directed to a site about love horoscopes and weird ads. I can't access the wp admin login site at all. What I need is to get in to wordpress admin - set up the new theme and get the connection between 3ix and wordpress sorted out. I want to work in an easy way through wordpress and I need to be able to access it.
