Automated Teller Machines or ATMs are generally pretty easy to use.
But starting around nine Thursday morning, something went wrong.
If customers went inside, they came right back out.
At an ATM - same story.
"Yea it's a little confusing, it's frustrating," said Bank of America customer Eugene Roberts.
Bank of America customers across Southern California are having withdrawals from making withdrawals.
"All the systems are down. I can't use my ATM card, I can't withdraw money, I can't transfer funds, I can't do anything," said customer Maria Velasquez.
We tested the theory ourselves and we got cash, but others weren't so lucky. Roberts couldn't even view the balance of his savings account.
"I tried doing that with my account, a couple of times with my savings and everything else and there's no balance inquiries or anything like that," he said.
Bank of America spokesperson Tara Burke declined a phone interview, but sent an email calling it an "isolated incident" and said customers could still access their accounts.
Roberts experience didn't match Burke's statement.
"They just said that they don't really know what the issue is, and they don't know when it's going to be back up to normal."
