I too have tried to get hold of them and found it impossible. I have contacted my credit card company to stop accepting their charge only to find that they can't do that. They did give me a FAX # 305-397-1155. I ask them is I faxed the company and stated that I wanted to cancel the auto ship, if that would be enough to prove they received the cancellation. The cc company said absolutely and to be sure and keep the fax and the confirmation it went through. Also, they gave me an address - 3029 NE 188th St, Suite 525, Miami, FK 33180. Nutri Blvd's regular number is 819-483-0467. Hope this helps someone else.
