Do Not Trust This Bank In my experience, Arsenal Credit Union is not trustworthy. Money was taken out of my account without my authorization, and when I tried to get answers, I was given the runaround instead of real help. There was no clear explanation, no urgency, and no accountability. It feels like they make it difficult on purpose when they mess up, and the burden is put on the customer to fight for their own money. I’ve never dealt with a bank that made me feel so powerless and ignored. If you value transparency, security, and basic customer service, I strongly recommend looking elsewhere. I regret ever banking here

Called about an auto loan I had through them, the supervisor (I don’t recall her name) decided to hang up on me instead of offering any other solutions that would actually work for me. They make everything by a hoop you have to jump through, very sketchy and disingenuous company. This isn’t the first time I’ve had issues with them but it is most definitely the last time. Incredibly unprofessional, would never recommend, definitely never using them again. I’m quite disgusted with the entire company

Do not try to get an auto loan through this credit union they are a joke. Wasted a hit on my credit score and they turned me down cause I had to good of a credit report history and claimed it was because of bankruptcy and that’s a lie because I completed a chapter 13 in November of 2025 and being February of 26 it shouldn’t have matter

The Staff at the Arsenal Credit Union in Swansea were so welcoming and helpful to me, they helped set up my account and were attentive to my children so I could focus. Looking forward to working with Arsenal Credit Union
