I've been a member of Achieva Credit Union since 2008. It was my first bank account when I turned 18, and they gave me my first credit card. I have always had my questions answered. My only complaints about the company is that there is no 24/7 customer service, and that there always seems to be a long wait to make a deposit. For those complaining about the debit card fee, that was actually discontinued effective August 1st, 2014.
Out of all of the credit unions and banks I've been with, they are the only ones that don't require me to use my debit card a certain amount of times to waive the monthly service fee, they don't require a direct deposit, or a minimum balance to keep my account free.
