Pierre, SD: Attorney General Marty Jackley is warning South Dakota consumers to be cautious of robocalls targeting cell phone users with a scam that implies that their debit cards have been comprised. The automated phone message prompts the consumer to press a number one to unlock the card. Once the number one is pressed the consumer is connected to a live person who the requests the debit card number, current address and confirmation of recent transactions. The scam artist then asks for a PIN number in order to reset the card. Consumers should refrain from giving out any personal information and to hang up without pressing any numbers.

If you believe you are a victim of this scam or need any additional information contact the South Dakota Consumer Protection Division at 1-800-300-1986 or consumerhelp@state.sd.us. Anyone who has given out personal financial information should contact their financial institution immediately.
