Avanti Skin Renewal Misleading words to lure me into website Internet

I was on my Facebook account when a picture of Joanna Gaines came up with what appeared to be her skin care products. It stated I could get a free sample, just pay shipping! So I thought why not try this! I was only interested in the skin cream and was ready to pay the shipping cost for just that.  Next thing I knew they are pushing to purchase additional products. Not even knowing how it happened, it said I purchased the eye cream as well! Once you are in the site you cannot go back, you are stuck in there! Good thing I didnt get caught purchasing the 35dollar item as well.  I still havent opened the product mind you when I get an insufficient fund notice from my bank.  I call them and they stated to call the company first to try and resolve. So I did and a rep stated that I checked a terms and condition box stating I was 18, and I should have read the terms and conditions. I told him I dont even recall seeing those terms and I feel the site is very misleading, plus I could not afford paying over 180 dollars in skin care products. After many minutes he says he will drop me from the every 30 day renewal plan, and first said he could give me a 30% discount, which went to 50, then firmly stayed at 75%.  So Instead of going back to my bank, which the rep told me would be a waste of time, because the company wouldnt refund me, I took the 75% off. He said i would only have to pay 22.50! So I said 22.50 total? He said yes...So I get the credit and its for $131.94, which means I still paid $44 dollars!!! plus the 10 something in shipping charges. I chalked it up to live and learn, but I feel stupid and im still upset about it!!
