I read an article about a brain-enhancing supplement that had endorsements by Steven Hawking, Bill O’Reilly, and Dr. Oz., I ordered a 15 day supply paying only for the shipping. They also sent a Sleep Supplement in addition to the Elias Cognitive Supplement. There is no phone number nor email address on the invoice. I have looked on the Internet but cannot find a phone number. I have read some really bad reviews from other users. I hope you can find a way to locate them and let me know how I can contact them and cancel my order before they start hitting my card for more money. They will charge me $92.00 if I cannot cancel within 13 days.
