Platinum realty Avoiding me Jamaica New York

I responded to a posting on craiglist for a three bedroom Apt.  The price was reasonable and the place was ok so I put down a deposit and was told if i was not approved that i would receive my money back.  I also got a receipt stating the same.  I was told that i would be notified several days later of the outcome.  From then on it has been hit and miss with the real estate agent.  Not returning calls or text.  Then finally responding just to delay further.  i have visited his office several times and he has not been in the office.
