Sulekha.com — nipun patel scammed me of money

Nipun patel said he had a room at 890 bush st and i paid a month's rent and security deposit ($700 + $750). He requested the payment be done by zelle ([protected]@aol.com). Once the payment was done, he said the leasing community had doubled the security deposit amount and i would need to pay additional $750. I called up the leasing office of the apartment to learn there was no person living with that name. I told nipun i could not move in for personal reasons and requested a refund. He has stopped responding to my emails or messages since. Please suggest what i can do. Thank you.
