This one really urked me. I received the free sample. Tried it, didn't work. Didn't mail anything back either. About a month later I received a tube of Vanish that I did NOT order. Along with a bill. I sent it back, postage due. Then I kept receiving bills saying I had to pay for it. Finally, I wrote and told this company off. I explained everything and refused to pay the bill. I never heard anything again. These offers are ridiculous and are just trying to get you to use their product. When you receive a free sample from anywhere that you did not ask for, put it back in the mailbox, mark it REFUSED. Hopefully that will get the message through.
