I completed the 5 day detox, waited the extra 1-3 days as recommended and followed all instructions they sent. I had already abstained from toxins 2 weeks before beginning the cleanse and still tested positive 3 days after completing the 5-day detox. I called the company to request a refund; the c.s. rep talked over me the whole time, accused me of lying and even hung up on me. Furthermore, the rep did not want to refund me and I had to contact another department in order to be assisted and receive a refund. I have also reported the company to the Better Business Bureau (BBB) for false advertising of company products. This company is a scam; don't waste your time, money or patience.
