Unaouthorized debit to my credit card account

I have been considering using the services of [URL Removed] In order for me to view there products and try there sample audio books it was necessary for me to disclose my credit card information to [URL Removed]<br> And do you know what ? Well, today they debited my credit card for an amount of R172.98. Completely unauthorised. ***** COME BACK.<br> I have made no purchase from them or given them authorisation to debit my card. <br> What they have done is downright theft. Just like a pickpocket ***** from you when they think you are unaware. <br> I gave them my credit card details in good faith and they stole money out of my South Africa MasterCard account. What a bunch of *******. I am going to reverse that debit to my Master card account. [URL Removed] PUT MY MONEY BACK YOU *****.
