The Company advertised 100% guarantee 30 day something like that. They advertised complete lies to get you to order that first couple bottles. I wanted to send back it was totally a placebo type of IQ boost. Nothing as they advertised it was a total hook. I was not happy at all I looked everywhere for any information about the company that I had done business with no email no company name in any of the packaging it had a fulfillment center through Tampa Florida. Then I get a box in the mail with two more bottles and another charge for $89 I had no idea where to send it back to you so I spent a lot of time writing up a letter and spending almost $10 to send it back to the fulfillment center with a note exactly about the story I'm telling you now. I called a fulfillment center they said they didn't fulfill for that IQ boost they said they would not be able to cancel any ongoing charges to my card or any subscriptions anyway they were just a fulfillment center. I finally got the name of the company orderbarnleynutrition in florida with number *******753 finally a number - I called and the person answering the phone I could barely hear her and she wanted to know my ZIP Code then she wanted to know my name and I told her no I didn't want to tell her anything until she told me who she was and what business I was talking to and she refused to tell me anything in the background I heard I got oriental voice yelling at a customer on another line apparently arguing with somebody with the same type of conversation that I was having with this was very mysterious for sure. I had to cancel my credit card but I'm going to completely cancel the card me they issued me a new credit card number but I'm going to completely cancel the card so they can't keep charging my card for something I don't want and I don't trust the number on the person on the other line of the number.
