Well, I feel that I've been very silly and it's been an expensive mistake. The 'free trial' arrived and I've stopped taking the tablets anyway. I've now received another delivery that I did not authorise. My credit card has been charged with a total of $197.99 USD. I'm retired and that is a lot of money for me! I've requested my bank not to accept any more debits from this organisation, so fingers crossed. I wish I had an email address so that I can chase them for my refund. Can anyone help?
