Derma Nu Charged my credit card for "free" sample, $89.00, refunded half whenI complained then charged me twice more! Clearwater Florida Internet

 I ordered a "free sample" per Facebook ad and was subsequently charged $89.00! When I called the company and freaked out, after much arguing with representatives, I was refunded half of the $89 and told the order would be cancelled and I wouldn't be charged again. Surprise! I've received two more shipments and been charged the $89 twice more!! I'm disabled and on a limited income and definitely cannot afford these ridiculous charges! This company should have a class action suit thrown at them and I would gladly take part!
