Some info about the Better Business Bureau lifted from the wikipedia
In 2010 ABC’s 20/20 reported in a segment titled “The Best Ratings Money Can Buy” about the irregularities in BBB ratings. They reported that a man created two dummy companies which received A+ ratings as soon as he had paid the membership fee. They also reported that business owners were told that the only way to improve their rating was by paying the fee. In one case a C was turned to an A immediately after a payment and in another case a C?minus became an A+. Chef Wolfgang Puck said that some of his businesses receive F’s because he refuses to pay a fee. Ritz Carlton, which does not belong either, also receives Fs for not responding to its complaints.
In response, the president of the Council of Better Business Bureaus has stated the BBB ratings system will cease awarding points to businesses for being BBB members. The national BBB’s executive committee voted to address the public’s perception of the ratings system. It voted that the BBB ratings system would no longer give additional points to businesses because they are accredited. It voted to implement a system to handle complaints about BBB sales practices.  Despite the vote, the BBB website still states that points are taken away if accreditation is lost.
In Canada, the CBC News reported in 2010 that Canadian BBBs were downgrading the ratings scores of businesses who stopped paying their dues. For example, a moving business who had an A rating and had been a BBB member for 20 years, dropped to a D?minus rating when they allegedly no longer wanted to pay dues.
BBBs have been accused of unduly protecting companies. If a branch does not act reasonably on behalf of a consumer, a complaint may be filed with the Federal Trade Commission. However, recent reports have suggested that the Austin chapter of the Better Business Bureau refused to resolve complaints against companies if customers do not pay a $70 mediation fee.
