A representative from Target headquarters told CBS Atlanta the retailer is working with state and federal agents to get to the bottom of a recent security breach.
The store said some 40 million customers may have had their accounts compromised since Nov. 29, Black Friday.
"We continue to experience a high volume of calls to our call center and we have more than doubled the number of team members taking calls," said Target spokeswoman Katie Boylan via email.
Target gave credit customers a 10 percent discount of purchases over the weekend. It would not release sales figures but said customers were appreciative.
Not all customers agree.
"I have aTarget card and I didn't use it the other day because I was too afraid to," said Kathy Bennett. "I was actually a little irritated because I asked the cashier, 'What's the deal? What are you all going to do? Should we not use our cards?' She said, 'We don't know anything.'"
Bennett also banks at J.P. Chase Morgan, a bank that has now placed limits on how much customers can spend. On Monday, Chase lifted its cap and will allow customers to spend $250 at the ATM each day and $1,000 on credit card accounts.
"It sucks. It's awful," said Tyler Dixon, who is also a Chase customer. "I do think we live in a time where security is hard to come by. Of course, it doesn't give me any kind of easy feeling knowing that."
Chase said it will contact customers who have had a security breach via mail or email.
"I have alerts on my accounts that will let me know if someone else is looking at them and that's the best we can all do," said customer Lytia Howard.
