So, I used Quantum's mobile deposit for the first time, as I am unable to visit in person. 1st they rejected it, because I didn't put mobile deposit only and Quantum name on it. Re did that, then 24hrs later they put a 6 day hold on it!!!!!! No where when I was making the deposit did it say that, even though it is in their policy (so they told me when I called) so now they have my money held for 6 days. Their response, we can take it off hold and you can take it somewhere else. HOW can I do that....you made me put mobile deposit only, Quantum credit union on the back!!!!! Not helpful at all and NO MONEY!!!!! Constantly changing things. Would not recommend using this credit union at all.

Terrible place if you are considering banking here do not! The reviews do not lie. They are not clear on their policies at all. They will take fees at any turn they can. In total they have taken $60 out of my account and refuse to even consider refunding a single dollar. When I called about it the customer service was horrible she was snooty throughout the entire conversation and unwilling to listen to my circumstances. I will be closing my account as soon as I can. I also looked through reviews someone 7 years ago experienced the same thing with PayPal letting cancelled transactions go through before refunding which resulted in them piling up nsf fees. I really do wish they sided with the customer but clearly they are filled with greed.

EDIT: They reached out to me and resolved the issue quickly and efficiently. The worker who contacted me was very helpful, thank you! Seems it was just a misunderstanding. Been using Quantum for years, typically I do mobile deposit because it's convenient and I typically get the money within a couple of hours if not next day. I went in today to deposit my paycheck because I was passing by anyways and my funds won't be available until 2/18? That's ridiculous the pay check was ~$2 more then my last mobile deposit that I got same day.

I had a fantastic experience with Tammy Wilson. She responded incredibly quickly and provided all the information I needed without delay. Her efficiency and attentiveness made the process seamless and stress-free. I highly recommend Quantum Credit Union for their exceptional service and dedication to their customers. They truly go above and beyond to take care of you.

I have been with who is now known as Quantum Credit Union for years. The customer service I received at the branch and on the phone on 3/22/2025 was horrendous. I now question the systems in place to protect me from fraudulent charges.
