This company use ad to lure you to get a free sample. Then if you do not call to stop, they'll keep charging on your card. Be careful! They just want to use this way to skim people who have a busy schedule and do not check on their card.
I called to ask them to stop and they have not still not sent me a confirmation number through email. I have to send two email over and still waiting.
It's a method of scamming people. Be careful! do not get caught.
I really think the government should do something to this kind of scam.
