A complete scam. A negative opt out was in the fine print, along with the opt out toll-free number. The number was non-functional during and beyond the 2-week trial period. After searching the internet to find the offending company, I thought to actually look at the ColonRX bottle, and there was the SFNNutrition URL. During an online chat, their rep simply hung up on me when I asked how they could justify charging when the customer had no way to opt out. I have lodged complaints with the FTC and IC3, and asked for a charge reversal with my financial institution. Avoid like the plague!!! These people are thieves. read full review »
