My dad was a customer at this bank for several years before he passed away. Between a complete lack of communication, almost zero response from calls and emails trying to understand what I needed to do to close his account, I feel as though I was treated as an absolute inconvenience! Do not recommend this credit union at all!!!!!!!!

AVOID AT ALL COSTS. I hate leaving bad reviews, but I would avoid Rimrock credit union like the plague. I sent an email over a week ago inquiring about a promotional interest rate. Never heard back. Regardless over a week ago I filled out an online loan application. Both on the application page, and on the contact us page, it states you will hear back from a banker within 1 business day. I called and left messages to have a loan officer call me back and have never received a call, or email. However they still pulled my credit. REALLY? I don’t understand how this is even legal, much less decent or the right thing to do. TO THIS DAY I HAVE NEVER BEEN CONTACTED BY ANYONE?!?! How is this even possible that an institution could be this bad? My only other dealings here have been when I have sold a car to someone who was getting a loan there, and I had the worst customer service from a lady who had paper files stacked to the roof in her office. She basically scolded me and made me feel terrible I didn’t understand the process. Quite unprofessional to have customer files laying all over the place in this day and age of digital scanning and documentation. How is it safe you just have customer files laying everywhere for anyone to grab at anytime? I really wanted to give them a chance, but the low interest rate really isn’t worth it. Take your time and shop other credit unions like Altana and Valley Federal where they treat you like a customer, not like a problem. Hopefully management sees this and contacts me directly to discuss further, however they haven’t responded to any google review. There is no contact information or even a listing of who a manager would be. Lots of problems and lack of oversight going on here. YOU CAN DO BETTER! MUCH BETTER!!!! HECK hire me and I will turn loans over all day. Why offer something you can’t deliver on?

At Rimrock Credit Union, the person comes first! I have been a member of RRCU for over twenty years. They have always treated our family with kindness and courtesy. They have been making tremendous strides in the past few years to update their online capabilities and account offerings. They may not have all the perks other CUs offer just yet, but they make up for it ten times over with their service! I have never had a bad experience. Recently, I went into the office to get a auto loan with Brandi. The entire process was quick and easy! She was also able to offer me a significantly lower interest rate than other banks & CUs I had researched.

Was looking up some info real quick on the credit union and noticed the reviews. I clicked on them to see what was written and was surprised. I have banked here for 20 years. I don't believe I have ever been treated poorly by anyone at the bank. Over the years, there have been a few banking errors made, all of which were rectified. These people meet me with a smiling face every time I enter.

Rimrock Credit Union has been there for me through and through. I used to deal with Paula, until she retired. She was always very sweet and straight forward with me. RRCU has always prevailed in helping me when I needed it the most. In a time where I thought I would never be able to get a loan without a sky high interest rate, RRCU was there. I've been with RRCU for about 10 years now, several loans later I still have a great rapport with their staff. Since Paula's retirement, I now deal with Brandi and she is the best! She always calls me back within a business day and is very informative. The teller's are always helpful, prompt and courteous. I have even moved out of state for a few years and still very pleased. Things have changed with RRCU, but not entirely bad. Still a little slow on the technology aspect to online banking and mobile banking. It does take awhile to get used to compared to another bank I deal with (only for the convenience when traveling). With their overall performance and longevity with their integrity, I'm more than satisfied and will never deal with another bank again (unless they do not offer the services I desire/need).
