Surprising backlink building result

I ordered a popular backlink package from BST for $99. The site is a new one and I gave only one link for building. What happened right now is that the link which I gave gone way down in rankings and is almost not ranking for any of the keywords it was ranking before the build. Instead of that link, homepage url is now on the rise and has been ranking for many of the keywords which I gave. So what should I do to get back the ranking of my needed URL? It's kind of a tragic situation for me

Depends. What package, how many links, what was existing profile like?
Maybe it's dancing, maybe that package topped your anchor text percentage over the edge..... Need more info.
