Made a one time purchase of this product on Ebay. Lo and behold yesterday I received a shipment from Mineral Science as "outlined in my club membership" . What club membership ? Not only was it not wanted and not ordered, My credit card was charged without my authorization !!! Communication with this company via phone and or e-mail is futile. I found the web sight to cancel my "membership", I also found out via the BBB website that they are no longer accepting complaints in Texas. I was referred to the BBB site in Pa. There is a toll free number...[protected]. The e-mail address of the head officer is ...firstname.lastname@example.org. I think a class action suit should initiated against this company and charges should be filed with the Post Office as they are committing mail fraud.
