Complaint Review: HCG Extreme

I am being ripped off by HCG extreme that sells some kind of diet supplement. This company somehow has managed to get ahold of all of my personal information and my credit card.  They have sent two boxes of their product so far.  I never ordered this in the first place!  I have tried to get ahold of their company via web site and phone.  No one ever picks up their phone there.  They let you leave a message and tell you they will call you back but, they don't!  Each shipment I am receiving is around $90.00.  Help I don't know how this started or how to stop it!!!  I do know I am not the only one. There are a lot of people being ripped off by them that I just found on the google page where their site is also.  What are we to do so they do not get any more of our money?!
