SAN DIEGO – Wells Fargo customers were unable to use the bank’s online service, app and debit cards Thursday due to a power shutdown.

@WellsFargo Are you guys having some problems today?? Online banking seems to be having an outage. Along with mobile. — Dudepie (@Dudepie85) February 7, 2019

@Ask_WellsFargo everything is down. Called 800# and spoke to Michelle. It seems that she has been dealing with some really angry customers, so she answered my call with a hilarious ready speech about how WF is well aware of the issue. I’m dying & no longer angry. #thanksMichelle — 🇬🇹Tired, just tired 🇵🇷 (@Carajoboricua) February 7, 2019

@WellsFargo how about telling your customers when there is an outage. Debit cards, online banking, text banking, mobile app. None working. — kerry 🇺🇸 (@americanestdude) February 7, 2019

This was the second time in a week Wells Fargo customers had an issue accessing the bank’s online system. The bank apologized on Friday, February 1 about the system outage.
