Revitol The hair removal cream burnt my skin and they said it would not. CA Internet

I placed an online order for Revitol hair removal cream on 2/22/16 because all the research I did said it was a safe and painless product.  Well when I used the product it burnt my skin and left bumps and dried areas.  I called the company to return the product and the customer service rep told me that once a product has been opened they do take returns.  I asked her how do you know if a product works if you don't try it?  She said I should have read their return policy.  After the rep was really rude they dedcided they would issue a $7.00 credit when I paid $51.88 for the product and as of 3/23/16 I still have not received my $7.00 credit.  I would never recommend some else to use this product.
