Alteril is a scam, it DOES NOT WORK, they will keep charging your account!! you MUST CANCEL the card that you used to get the free sample, this is the ONLY way to stop the charges. If all the people do this, this fraud company will be out of business and maybe the gov will investigate this company. I just got off the phone with my bank and cancelled my card, and they will send me a new one with a different card # so this fraud of a company will NOT be able to charge anything to my card, as they will not have access to my new information!! PLEASE!!! cancel the card that you used!!! read full review »
