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”

I loved Great Western Bank! I e been with them for years! But this new bank is HORRIBLE!! Their customer service is Absolutely Ridiculous!! I waited the first time over 20 minutes never spoke to anyone so I hung up. I called back and was on hold for 38 minutes before I spoke to someone then was put on hold again for another 30 minutes then wasn't helped out at all!! I am switching banks immediately!!
