Bellabrite offered free trial package, then charged my account for $78 and change and the product does not work well. Boulder, Colorado

I saw an ad for this Bellabrite teeth whitening and is represented itself as a free trial. It looked good, nothing fishy and did not check it out. The product is NOT free and in hindsight, is a scam because this maggot group of people, who prefer to rip off consumers instead of actually offering a legitimate product offer,  has been getting away with it for better than 4 years. The next day an unauthorized charge was made to my account for  $78.41. This rancid company has been operating for at least 4 years and my main concern is HOW? Why hasn't law enforcement shut them down? Is Colorado that weak and impotent that some action can't be taken. How many people need to be robbed before these scumbags are stopped? How are we to recover our money??
