If you receive money that you’re not expecting, check with your bank or credit card company immediately. No one should be depositing funds to your accounts unless you are expecting a refund or deposit from a legitimate source. Call your bank or credit card company immediately if you see an unusual transaction. And check your online accounts frequently. If you do online banking and see a transaction that doesn’t make sense, it likely is fraudulent.
Although legitimate mistakes happen, it’s more likely that someone is trying to defraud you.
