I recieved a letter in mail about my acct having unauthorized uses so I called my cu and they do not have anything in their system for the case number I gave them. This is a scam!
Its not a scam, they are a fraud house that sends notices from credit card charges from smaller banks that cant afford to have the monitoring done in house. Its safe to call. They will ask about recent online charges on your account and you just have to verify that you made the charges. They already have most of your personal info from your bank.
