    Can’t believe this place has any customers. Had issue with business mobile deposits. Threatening to pull business and personal accounts was only reason it was fixed (took a month). While depositing business and personal accounts, telling made us show ID, while two other customers inside and other drive through customers were not asked. Employee turn over is unbelievable! Definitely changing to another financial institution!

    Though this doesn't pertain specifically to this branch, but to first interstate as a whole. It's extremely frustrating how often I cannot access my online banking. "Service unavailable, no account information found" especially on weekends. We live in a digital world where hackers are better than ever and it's terrifying the amount of accumulated time I'm unable to see or access my online banking. Every other aspect of this bank is "normal", but this one aspect alone may be enough for me to switch banks.
