I responded to a free trial for a teeth whitening product for $6.95. I did not see anything about canceling in 14 days or I would continue to get product and be charged. More product came in days after and my credit card had been charged another $79.99. I called Natural Source and was told there was nothing I could do because I didn't call within the 14 days. I have their invoices and nowhere does it say anything about that. I have not opened the product but they told me I could not return it for a refund. read full review »
