Purity Products Duromax Charged for "free" samples, gave my email address to a sister company, and then charged for samples I could not decline. Venice California

I heard radio offer of a free product sample called "Green Tea CR" from Purity Products.  I called and requested the sample, giving my credit card number to cover a $4.95 shipping fee.  I declined a suggestion of regular shipments every month, saying I only wanted the sample.   

I later recieved an email offer of free bottle of "Duro Max.  Being 75 years old, I thought "what the hell, I'll try it."  Immediatly it automatically supplemented the order with a sample of "Nitric Oxide Booster"  with no chance to decline the extra product.  I paid for shipment on these products also, given that the product was "free"   At this point I thought the 2 vendors were separate and distinct  

About a month later my bank called to ask if I knew I had been charged $87 twice on my credit card by a company called "Fit Trial" who had evidently contacted annother company called "Fit Life" and given them my phone number.   I did not know of either Fit Life or Fit Trial but deduced it was somehow connected to my "free" trial pills.  I had recieved no further pills in the mail.   I immediatly called both companies  and was told I had signed up for shipments of pills at full cost.   I had recieved nothing but the "samples"..   It became obvious that I was speaking to the same "customer care" dept in each case and they were all the same company.  After much protesting and demanding a full refund of the charges, they finally agreed to refund the charges to my credit card.  

The pills got my dander up - if nothing else.
