Company offered me a free sample if I payed for shipment and then used the credit card that payed for shippment to charge me for entire course with out my permission. The free sample ended up costing me over a thousand dollars. I canceled my credit card and they are requesting $137.76 they claim are unpaid and due. They claim I can pay www.stroll.com to keep it out of collections, but the site is always down. They want a new credit card number given over the phone, but I don't trust them with my credit cards.
