Evaluation Solutions Does NOT pay JacksonvilleInternet, Florida

I have completed work that has been accepted by the company and not paid for it.  The broker price opinions were completed in July 2012 and payment should have been received in August.  I have tried calling the company, but the company directory does not list the departments following the individuals name.  I randomly selected 4 employees to ask for help in being directed to the accounts payable person, but noone has responded.  I found rip off report and a similar complaint.  At that time Evaluation Solutions said the non-payment was due to a missing W-9 form.  I checked my account and that information is there.
