Rent.com Don't count on getting that $100 reward card!  Internet

I utilized rent.com to locate an apartment.  I filled out all of the required information.  I also contacted the apartment directly using the number that was listed on rent.com.  It is the property's direct number.   I completed everything online regarding claiming the reward.  They tell me that the property is telling them that I didn't get the "lead" from rent.com but that it came directly in through their site.  They said that if I object to this to contact them back (them being rent.com) and they will re-contact the property manager.  They then emailed me back after I did just that telling me that they cannot do anything else.  I spoke with the property manager who told me the same bull.  

I don't know what you have to do to claim your "reward" and make it work as I did everything exactly as the site indicated and have been repeatedly denied.
