I have a travel trailer loan and every month I get a harassing phone call from collections even if I pay on time . The last collections guy I talked to says I need to pay my loan 5 days early or I will get this phone call every month . These calls are rude and this CU is the worst I've ever dealt with . I will be doing a refi wit AZ One CU as soon as possible and will never do business with this bank ever again . I don't pay loans late , never have and I shouldn't have to deal with rude collectors every month just because I chose Alliant to finance my Trailer . You can look and see more reviews her talking about these rude phone calls , I'm not the only one .

24/7 skilled human, good promos
I've been with Alliant about 2 years. I cite a number of interactions in this review but the most recent were yesterday (used a promo, used their credit card, talked to customer service).
Like many people, I like their high-cashback credit card and their CD rates which are often near the top of the range. That's why I signed up. But there are 5 other things I really like about them that I think are less well-known:
1. Promos. Their credit card has some pretty good promos as well, and they've credited easily for me in the past. Recently I've gotten a limited-time 3% on everything, and a 10% on mobile wallet up to a cap. Beyond the card, they also gave me some free AD&D insurance, which I think is fairly common for credit unions but still nice.
2. Security with account linking. They have 2 features I really like: #1 I can link an external bank account so that it cannot be used to make transfers but can only be used to autopay my credit card. I like this because then someone who hacks my Alliant account wouldn't be able to drain my external bank account. #2 They allow linking of bank accounts with micro deposits. This is still fairly common but becoming less so. They also allow Plaid, which I don't use but I like having options.
3. They sent me free checks when I signed up!
4. They allow secure messaging. This is pretty common but getting less common. They also get back to me quickly when I ask for help via that method.
5. Great at handling "crises." I've had three situations where I've needed help right away at night, one of those was on the weekend. Each time, I was able to get immediate help from someone on the phone who KNEW WHAT THEY WERE TALKING ABOUT. There are other banks like this but I think Alliant is about the best I've seen in this department.
Here are the three cases:
1. I linked Alliant to my online broker, then the online broker screwed up the account number but still approved the link. Then I tried to buy something on my broker, it went through and then later the broker was like oh no, your funding source didn't work and now you owe us money to cover the purchase we already made. It took me a while to figure out that the broker screwed up the account number, but in the meantime Alliant was able to give me all the detail from their end that night.
2. Credit card fraud situation. I had a random weird charge show up on my credit card, called them, they immediately did the standard close-and-send-you-a-new-card process and also refunded my account within a couple days.
3. Website issue. I was having an issue with the Alliant website, it was glitching out for me and I was close to my credit card payment due date. I called on Saturday night and very quickly got someone who was able to process a payment for me over the phone and explain options I would have to get around this in the future. The website issue went away while I was still on the phone, so maybe they fixed that at the same time.
Beyond this, they have also always been "no BS" for me with large transfers. I always tell them ahead of time when there is going to be a big outgoing transfer or a huge incoming transfer. Then when I make the transfers, they go through.
They are one of two banks with whom I have resolved 100% of my issues with the first phone call.

Bad experience with their loan…
Bad experience with their loan officers. The few times I have called to try to work things out I get talked down to and told multiple different things depending on who I speak with. Really tired of hoping I'd get someone to truly help me and tell me all rather than call several times to get a full picture or all the options that available to me. Not very friendly or helpful and they give serious attitude, get a different job bud if you're tired of dealing with people on the phone.

Alliant oks fraudulent charge though they have $0 fraud liability guarantee!!
Alliant reported an unauthorized fraudulent transaction on my visa credit card. They sent me a new card, but never credited the fraudulent charge back to my account. Even after calling them 5 times they just obfuscated the situation. BTW they have a "$0 fraud liability guarantee" with Visa. Seven months later this same phony company got hold of my new credit card. This time Alliant let it go through. I caught it, now they are hassling me about this charge. This is when I found out they never credited the previous fraudulent charge.

Mismanagement & Mishandling of Consumer Funds
I opened this savings account as a condition to a loan I received. I kept the account open after the loan was paid just to have an extra savings spot. I attempted to transfer to my external account on Monday and was prevented due to a limit that was now placed on my account that it never had before.
I was given the run around and lied to numerous times about withdrawing my money from branches until I just decided to just close the account.
I requested that a cashiers check be sent to me overnight via FedEx. Today is Thursday and I still don’t have my funds. Upon calling for a status update I was just told that they made “Another Mistake” by sending my cashiers check via regular mail with no way to track it because they don’t get receipt's from the postal service, and let me clarify that we’re talking about over $10K which would normally require some sort of mail insurance, yet they charged me $22 TWICE for the FedEx service on Monday and the only solution given is to prolong the situation further by stop payments, form request, and reassurance of the checks. How does that benefit me or make me feel better when my bills are due?
I’d run far away from this institution because I couldn’t even find them on the NCUA research site yet they claim they are governed by the entity!! I believe this is a scam.

Several administrative issues
Several administrative issues. It took over a year to correct their error in not submitting funds into a CD account as requested. I made several phone calls and finally talked to a supervisor and stated I needed to file a complaint with the state. The second issue was that I always get a quarterly paper statement and all of a sudden I didn’t get one. I asked to get one (I do pay for this service). Then, the next quarter, I didn’t get one again. They stated that I asked for e-statements only. I’ve been banking with them for several years and that is not the case —I did not request e-statements. The third issue is I never received my paper tax form from them as is legally required. I called twice and I still didn’t get it. I’m sorry I put some money in a CD again; I will be closing my accounts there once my terms are up.

Miserable mortgage experience
Getting my mortgage transferred to Alliant has been a miserable experience. I was not provided with a member number to log in, and they are unwilling to provide one. Attempting to call in results in 45 minutes of transfers between completely untrained phone staff and zero resolutions. If anything goes wrong with my regular payments, or I need to change payment information or just obtain basic loan information, I am completely unable to do so and unable to fix the problem. Avoid this company at all costs if you are fortunate enough to be able to do so.
