    Went in to close an account because their customer service has been horrible when calling. The one standing who was helping me was very kind, but the dark haired woman who sits at a desk across from them interrupted, confused everything, and provided a perfect example of why I will no longer be banking with first interstate.

    Came in to exhange small bills for big bills and no one was in the building, the lady was hiding in the back yelling for us and then when we asked for bills she grumpily came up front and said no as if we interrupted her sitting in the back lol what a “bank”

    Kami Reiger the retail manager is a complete asset to First Interstate Bank! She's beyond proficient and adept at anticipating your needs and fulfilling them. She's a joy to interact with and I feel confident in her superb abilities in assisting me with all my banking needs.

    Only reason I give 2 stars if for the few great customer service reps they have. Other than that I dislike everything about this bank. Let's start with some of the reps at different locations that make me feel like my businesses inconvenience to them. Sorry you have to do your job? There aren't any available reps after hours via phone like most large banks (24 service or at least weekend service). I have troubles on their website constantly. Won't tell you the charges made because of the way is listed. Shows pending charge, atm, debit. ... would be nice to verify the charge. And I've tried on the desktop as well as ipad. Same results. Running balance only allies the several charges, to a few days previous. So basically when you switch to previous pages it doesn't show your balance at that point in time. ' You do the math here 'is my understanding of it. Last, I've been locked out of my account for making several large purchases (under $1000) in a day, Christmas season. It was a Saturday. Luckily I had cash saved because I was unable to use my card until the next business day when I could reach them. A phone call would have been nice before locking my out. Very frustrated w this bank and will be transferring very very soon. Hope This helps.
