Someone is using my website

I hired someone to promote several of my websites a while back and I have now discovered they set up bogus accounts on MyBlogLog under weird names and I have no access to them.

I own the blog/website names:
warmislands.com
weddingstrategies.com
freebiefanatic.com
ultimatebodymakeover.com
handyhouseholdhints.com

I would like to set up REAL MyBlogLog accounts for these sites.

If you look here you will see my company website lists me as the proper owner:
http://progressivesystemsinconline.com/

Please advise how these can be fixed. I discovered this trying to change my current profile from using freediot.com to warmislands.com
