UPDATE: Computer Glitch at Nob Hill Grocery Stores Double-Charges Customers

If you shopped at this past Sunday, Nov. 6, there’s a possibility that you were charged twice for the same transaction.

The Raley’s supermarket chain, which operates Raley’s, Nob Hill, Bel Air, Aisle 1, and Food Source stores, notified customers of the problem on its web site and through its e-mail subscriber list Monday evening.

The company blames a technical problem for the double charges, which affected debit cards, credit cards, gift cards and EBT cards.

"This situation was caused by a technical malfunction and not by a security breach, so no personal or financial information was at risk," said Raley's spokeswoman Ashley Zepernick in a statement Tuesday.

Zepernick said the company is hard at work processing reimbursements for the extra charges.

"We are devoting all of our resources to resolving any duplicate charges as quickly as possible, including extending the hours of operation at our Raley’s Service Center in an effort to best serve our customers, and we have increased the size of our call center team to better respond to our customers," she said.

"All duplicate transactions involving debit cards, credit cards and EBT cards that occurred at all of our stores on Sunday, Nov. 6, have been sent to our card processor to begin the reimbursement process," she explained. "Once completed, the duplicate charges will be immediately removed from all affected customers’ accounts; however, the actual processing time may vary from bank to bank. We are still working to refund customers who used mixed tender for their transactions - for example, first used their credit card, and then paid with cash."

Nob Hill customers should check your bank statement to see if you were hit with the extra charges - though Zepernick warned, because of the technical problem the company's systems experienced, the extra charges may not show up in customers' accounts until Tuesday, so customers should check frequently.

If extra charges do show up in your account, you can notify the company online to have the charge removed, or call the Raley’s Service Center at 1-800-925-9989.

"We deeply apologize for the inconvenience this has caused, and are committed to making this right with our customers," Zepernick said.
