Alpine White Nutra Foods Scam unathorized charges to credit card Internet

My most recent credit card statement shows a fraudulent charge of $89.99 on Aug.2,2011. The company's name is Nutra Foods, Ph. 1 866-9550878 UT.  When I finally got hold of someone at this number I talked to Heather in customer service. She informed me that Alpine White had me listed as an active member. I asked her to cancel my membership and she gave me a confirmation number and said she would also e-mail it to me. I have not received her e-mail yet. She said Nutra Foods could not give me a credit my account, Alpine White would have to do that.     May of 2010 I dealt with Alpine White about this same issue. I had to cancel a membership with them that I never requested. At that time they had charged my credit card account $62.90. When I tallked them they said they would cancel my unwanted membership and I would receive a credit to my account within about 15 days and the woman said I was suppose to send the free sample (free sample with no obligations) back to Alpine White. I did not send the free sample back that I had to pay the shipping on for them to send it to me. That's how they got my credit card number.   They didn't credit my account and my credit card had to dispute the original charge. Now they will be disputing Alpine Whites fraudulent charges again.  I believe this is a scam! I hope this will be finished with this scamming company soon and for the last time.
