I got charged by Elitepack for $24.82. I made some calls and found out that Elitepack and World Club Fitness are the same. Apparently when I signed up with Dazzle Smile, I agreed to become a member of World Club Fitness. I asked Dazzle Smile if they had given my information out to other companies, and they said that I signed up only for World Club.
It seems that other people who are having these problems are getting charged from companies such as Kitaccess, Elitepack, and LuminsWhite. I want to believe that it will end with ElitePack, but I may call these other companies to see if I've accidentally became a member.
