Pyramid scheme victim need advice

oohlala

So I was scammed into doing this 3month coffee trail thing weightloss. The supposedly Starbucks like coffee taste like a cup of oily crap and I wanted to back out but unknowingly was put into a 3month contract that if I backed out I'd have to pay more money. So I stayed and paid my dos becuase this was a friend's cousin and she was super sweet. Long story short I hated the product and their services and I've been seeing lately other girls posting her advertisement asking for "models" or people to "try" the product. It worked for her but didnt for me but that's not the part I worry about. I worry about all the false advertisements how you cant back out if you dont like the product. Dont want other people to make the same mistakes at me so I was wondering if I should say something cause I feel this is so wrong. At the same time I feel bad for her cause it's her livelihood and she's the only provider for her family.
