I responded to a free sample ad on the internet on 5/6/13. This was a product to help with thinning hair. The company name was Keranique. I was sent the bottles, but, when I read the ingredients, I found that it had an ingredient that was not to be used with a medication I take. I called and informed the customer service agent of this. She authorized me to return it. We sent it registered mail and received certification that they had received it. Instead of refunding my $79.95, I was charged another $79.95 on 6/3/13. I called back, and they asured me they would refund both amounts. It is now 9/15/13 and I have never received a refund for either amount.
