Authorities have issued a warning about a new scam in the area. Residents of Blue Earth County have reportedly been receiving phone calls from an anonymous person informing them that a credit card has been deactivated, and that a credit card number is needed to reactivate the cards. This is a scam. Financial institutions do not solicit credit card numbers from customers over the telephone. Authorities advise you to avoid giving callers any personal information, and the best thing you can do is to hang up the phone. If you do give out your credit card information, it’s recommended you contact the card provider and cancel the card.
