Bella at Home ripped me off for $92.13 Internet

I saw a small ad on Facebook about teeth whiteners and how you could get a trial size offer for $1.03 with $3.87 s&h.  I ordered it, gave my info and debit card information.  It did not mention anything about a 'membership' but 6 days later i was charged $92.13 for my membership.  When i called to try to get a refund, willing to return unused and unopened product, i was told repeatedly i was not eligible for a refund.  That i was supposed to have called and cancelled.  Well, i had no idea about that because i did not see it on the form i ordered the product from.  Or on the one giving my payment info on.  Also, they said within 10 days and it was only 6 for me.  But if i had no idea there was a 'membership' involved, how could i have called to cancel.

 I feel it is a scam for people who think under $5 is not a lot to lose even if it doesn't work.  Then they get you for just under $100.  People like me can't afford to lose that much.  Especially if you ordered both products mentioned in ad, since they supposedly worked together.  Now i have that much taken from my bank account from each company.  Huge ripoff!  When i called, i was repeatedly hung up on because i kept calling back.  They wouldn't give me a home office number or address and refused to give me any info about the company at all.  Very frustrating.  And cruel.
