"During the period when Trump University appeared to be active in the marketplace, BBB received multiple customer complaints about this business,” the New York area BBB and its national headquarters said in a released statement. "These complaints affected the Trump University BBB rating, which was as low as D- in 2010," the statement said.
"As the company appeared to be winding down, after 2013, no new complaints were reported. Complaints over three years old automatically rolled off of the Business Review, according to BBB policy. As a result, over time, Trump University’s BBB rating went to an A in July 2014 and then to an A+ in January 2015.”
So it ended up having an A+ rating in January 2015 because there were no complaints because it was essentially out of business!
Per BBB.ORG, Trump University, or Trump Entrepreneur Initiative as it is currently known, does not currently have any BBB rating, and,
! The Trump Entrepreneur Initiative is Believed to Be Out of Business ! .
