A potential consumer alert for customers of Schnucks.
Authorities say hackers may have stolen thousands of customers' credit card information after shopping at stores in and around St. Louis, MO.
But some of those customers say the grocery store chain kept them in the dark while thieves stole from their bank accounts.
Investigators say it's not clear how the breach was made.
"It concerns me a lot," says Theresa Lamb. "I don't like them even calling on the phone and giving their credit card number or their three-number-digits on the back."
Customers are weighing in on Schnucks' Facebook page saying they're outraged that the grocery store chain did little to let them know.
Two weeks ago, Schnucks released a statement saying it's cooperating and has hired an outside forensics company to investigate but what's still unclear is how many people may be affected and whether the company's credit card database was the target.
Lamb and her two daughters shop at Schnucks on Evansville's west side and says she'll be a little more careful when it comes to swiping her plastic.
No word yet if stores in the tri-state could have been affected.
Shoppers at Schnucks are being encouraged to use cash or checks until this problem gets sorted out.
