Teengfwhores review: Don't subscribe for their free trial

I found the website of Teengfwhores, and they offered free trial for 3 days. I signed up for this trial, but the moderators started to charge me for the membership and use earlier than the trial finished. I sent them emails, but everything was useless. No communication, no refund and I have no idea how to cancel this trial and fake charges, please, help me to stop this scamming company. Post comments and ideas. Thanks.
