– charged my card without authorization

I found a couple of charges on my credit card from and I have no idea how they got there. I never ordered anything from them and I have never even been to their website. I am thinking that they are just farming people’s cell numbers and then charging them for something that they never wanted or ordered. This is scam and I want to help put a stop to it. The charge was relatively small and maybe some people would just not notice it, but if they keep doing it they will end up stealing a lot of money.
