Just signed up. FYI, I was charged $9 when I looked at my Payment History on their site. It also stated $9 in the email they sent me. I had to do a live chat to have them correct my monthly charge to $6. For the $9 they already charged, I had to open a offline support ticket to ask for refund. Hopefully this will not be an issue, if so I will reply back here.
Got an email they refunded my $3 to my credit card and on their web site it shows -$3 in payment history. So everything looks good now.
