I am so disappointed at you closing the Weiser Branch. Myself plus others depend on the Weiser Branch for many reasons.How do people get cash when they never have used a debit card, or when you need to go in & talk to them about there account. Did you ever think about any of these reasons plus more before you decided to close this office? We have gotten to no every one of the people that works there. Sandi H. has been there almost since day one. She is one Terrific person. Then there is Josulfa, Kati, Terro. What are they going to do? I have been banking almost 13 yrs. at Mt. Gem., almost as long as you've been open. I really wish you would still consider leaving this Credit Union Open.
