THE BETTER BUSINESS BUREAU CHECKS UP ON COMPANIES, BUT WHO CHECKS UP ON THE BETTER BUSINESS BUREAU? BRIAN ROSS INVESTIGATES ON "20/20," FRIDAY, NOV. 12 ON ABC

"20/20" and ABC stations across the country investigate the Better Business Bureau, whose A+ grade is considered the gold standard for businesses. So why did the BBB in Los Angeles give a group of white supremacists an A+ while the Boston chapter of the BBB gave the five star Ritz Carlton Boston an F, with two complaints and millions of customers served? As Brian Ross reports, the BBB is under fire, accused of using bad ratings and the promise of improved ratings to sell memberships. "20/20" watches as business owners with C grades say they were told they could improve their rating by paying $425 for a membership in the BBB, and then watches as the business's score goes up to an A+ in one business day. It's a startling investigation that has some companies calling for the Better Business Bureau itself to be investigated. The exclusive report airs on "20/20," FRIDAY, NOVEMBER 12 (10:00-11:00 p.m., ET) on the ABC Television Network.

"20/20" will air additional reports, to be announced.

"20/20" is anchored by Elizabeth Vargas and Chris Cuomo. David Sloan is executive producer.
