I recently registered on a site called "FAST DIRECT DOWNLOAD" with a friend's credit card.
I was told to register for usd 5, after paying, I received an e-mail saying it was for a THREE DAY TRIAL. I sent them several e-mails to complain, but received no response from them. Two days ago, they charged the credit card usd 39 again and they said I have to cancel. I did and up till now I'm still waiting for a confirmation e-mail.
My friend's bank refused to cancel the credit card. So this a very big scam.
