Stemalogica review: Their trial is total rip off, they charged me for $150 per each small jar

I signed up for the trial from the company Stemalogica. I ordered 5 different products, but these jerks provided small jars of products. After that they charged me for each jar for $150. I was really shocked. I tried to reach these jerks, but no one replied to my emails. I wonder if there are people, who had the same thing. Maybe you can advise me how to stop these withdrawals. Please post your ideas and comments. Thanks.
