Blue Rocket Seo Faxed a fake invoice Houston Texas

Our company received a fax that looks like an invoice with our domain address and physical address on it.  The service summary is for Search Engine Optimization, Pinging Service, Directory Submission and Back-linking.  There is a Late Charge line ($0) and a Current Amount Due (February 2018) charge of $95.87.  There is even a "Please Mail This Portion with Your Payment.  Make Check Payable to: Blue Rocket SEO" stub at the bottom.  We have never heard of this company and definitely do not do business with them.
