Capital One banking customers are complaining of pending double charges and negative balances on their accounts.

The company's customer service Twitter account said that support teams are working towards a fix.

“Debit card bank transactions have us seeing double today,” the Ask Capital One account tweeted. “We are hard at work to nail down a fix as quickly as possible.”

Debit card bank transactions have us seeing double today. Rest assured our support teams are engaged & working towards a fix. Hanging on the phone? We know the waiting game's no fun & we apologize for the holdup. In the meantime, you can login online or via the app for updates.
