I cancelled membership of acai berry and have sent one bottle back. I have received two more which I am sending back at my expense. They continue to bill my credit card under the name of roper performance and j2 nutra products-both with the telephone number of 888 289 8740-one listed in Co (Roper) and the j2 nutra products in AZ. I want a refund to my credit card of $74.95 and $4.95. There siswno person with which to communicate!!!Gerald Prohaska
