We got an invoice in the mail for $2950 for advertising that we DID not do & nobody in our office approved. Also, there is no mention of anywhere we could see our supposed advertisement that we supposedly requested to even see it. We would never do this expensive of advertising. I searched the company on Google & found this site where other people had gotten similar invoices for similar services. I feel strongly that this is a scam. I looked up online the "Natural Resources & Mining Business Development Directory (2012 Edition)" that the add is supposed to be in and I can find no such directory online.
