Rev Share Media They have not completed work on an ad campaign in which I invested $500. Irvine California

I signed up with RevShare Media in April on the premise of substantial return on the initial lead investment of $500.  Things seem to be progressing until there was no return on the initial ad campaign.  Since that time, they have only communicated with me once, in spite of numerous attempts on my part to contact them and elicit a response.  I would like to lodge this complaint so that my experience is added to the record, in addition to any further action I may pursue.  Engagement with this company I would highly discourage!  It sound legitimate, but it does not appear to be.
