Hello; I just want to let everyone know "Acai Burn" is now "Acai Slim, " perhaps because there have been so many complaints about the former! Old phone numbers don't work, but the new (as of 10/13/09) number is 888-591-2190. Good luck! I called them and received help very quickly. Fortunately I had a tracking number and delivery confirmation to show it was returned w/i the trial period.
