Wells Fargo promised to fix by Saturday a nationwide computer glitch that left irate customers with incorrect — and sometimes negative — balances and missing transactions, according to a spokesman. It will also refund fees customers incurred because of the issue.

Some customers started their Friday morning routines hoping to see their latest paychecks directly deposited in their accounts. Instead, they had negative balances, a number of customers reported on social media, and a message from the bank: "If you see incorrect balances or missing transactions, this may be due to a technical issue and we apologize. Your accounts continue to be secure and we're working quickly on a resolution."

Funds remained available, even though some customers' direct deposit transactions were not showing on their accounts, bank spokesman Josh Dunn said.

Dunn did not say how many customers were impacted by the problem.

Wells Fargo is based in San Francisco but has its largest employment hub in Charlotte, N.C., and a significant presence in the Twin Cities.

It also is the nation's fourth largest bank by assets, at $1.7 trillion. That number is capped by the Federal Reserve, which restricted the bank's ability to grow in the aftermath of the 2016 fake accounts scandal.
