Genuinely terrible banking experience. Random account charges, service fees, and frankly unhelpful staff that tend to do the absolute bare minimum. Trying to deal with issues, the issues themselves consistently caused by the bank's shady business tactics, make this company an absolute headache. This isn't a bank, this is a business.

I love this bank! I've been with them for 20 years and they've always assisted with every random request that I have. Everything is done timely. There is a reason I've stuck with them throughout my travels. I live 12 hours away and still receive outstanding service! Marvin, Val, and Debbie have always taken great care of me!

Who keeps office hours ending at 4:00pm? Rubbish. Change office hours would make excellent review.
