Pure Saffron Slim Sent me another bottle of thier product without my authorization and charged my credit card for $48. Denver, Colorado

I ordered 3 bottles of Pure Saffron Slim on 01/02/13 for $98.  By the time I got the bottles and tried it, it was past their 30 day warranty period, so I was essentially stuck with 2 unopened bottles because the product upset my stomach.   On 04/05/13 I received another bottle of Pure Saffron Slim that I didn't order. 

I called the company and was told that they'd refund me 25% for the bottle that they just sent me.  I basically told them that I would have my credit card company reject the charge and would not pay for it.  They then said that they'd credit my card for the $48, but I really can't trust a company that charges my credit card when I did not authorize them to do so.  

I'd say beware of them and whatever garbage this product really is made of.   When I made my order in January there was no mention that they'd continue to send me their product and charge me for it.  I would consider it to be a scam.  At least one other person on here has had the same experience.
