Leanspa offered free sample and now keeps taking apx. $160.00 a month from my account. They avoid any contact from me. Orange, Connecticut

I answered an add for a free sample of two of the products they offer and I did recieve them. They did not tell me that I would be set up to recieve a bottle of each every month and that they would take $160.00 (aprox.) from my account. I am not even recieving the product but they ARE taking the money. I am going to have to close my checking account to be free from them. I have come accross other people who also had the same experiance as I am having and they also had to close there accounts. How can they get away with this for so long? Where is our government?
