Immediately notify your bank, credit union, or check cashing service. You’ll have to return the money.
If you deposited the phony check or money order, your bank or credit union may have already removed the money from your account by the time you discover the problem.
Explain that you’ve been scammed and request that no negative actions be taken against you (such as closing your account or reporting you to a checking account abuse database). If that has already happened, ask if that action can be reversed.
If there isn’t enough in your account to cover the loss, you could be sued to recover the funds. Try to work out a repayment plan.
File a report with your local police department.
Report the scam to the National Consumers League, which will pass the information along to law enforcement agencies.
