Dr ultra lean green
Charged for no product with no authorization

I ordered online for the slim, Dr Lean Green Tea, trial offer, and find they have charged my credit card for another $70 for I do not know what!

I was surprised this scam came from a link on the Oprah website/email service - I would have thought this organization would not allow any scams through their portal.

Any ideas how to contact them and stop the credit card deductions?
