USA BUSINESS CORP "I spoke to your CFO, he mentioned that you are the person to speak with regarding office supplies" Las Vegas, Nevada

I was contacted by a female who seemed very "fast-paced" and unorganized.  She mentioned that her business was going out of business and she was selling her stock at unbelievable prices. 

She mentioned that she had spoken on a personal level to our CFO and he referred her to me, that I am the person who orders items for the office.  I didn't want to question the CFO, so I assumed she was correct, since she knew his name.

I learned my lesson!  The items came and the price was almost $300!  The CFO had never heard of this company and my I feel like my reputation and credibility is now stained due to this error.
