Lumanelle I feel scammed Nationwide

I recently ordered the 14 day trial for luma hydrate and luma repair for $4.95 each, only for shipping cost for each, upon receiving the products, I did not receive any information that would let me know that I would be charged any additional money, I did not receive an account number or anything, I was then billed a month later on 3 seperate occasions $79.95,$89.95,$2.70. When I called, they informed me that, that was the price of the products if I wanted to keep them but, they had no idea why I was billed $2.70, I then made sure I cancelled the product even though I was never even given an account number
