Having tempted you with an introductory offer of £9.99 for a month, they will automatically take the following month subscription from your account at full price of £44 regardless of whether you have cancelled the subscription or not.
When contacting them to ask why they have taken money from your account they inform you ( after 4 days) of the process for stopping the renewal of the subscription, which you have already explained to them is what you had done in both the original e-mail and the reply to their response asking them again to refund the subscription as it is at the beginning of the month and is not required. At this stage you are simply put on an automated "please do not reply" e-mail.
I understand they have a very low number of new members and can only think this is why they are conning their new members with fake introductory offers that cost you twice.
