Please repost your question with more details.
Your question does not provide enough information to give you a proper answer. If you are saying that you paid a deposit and now the landlord is not returning your calls, I would try to stop payment on the check. If that's not an option, I would write a letter requesting your deposit back and state the reasons why. If that doesn't work, you can file a complaint with the State Attorney's Office, which may help by getting the authorities involved. If the "scam" is due to another reason, you would need to provide the details. Best of Luck! Jennifer
