- BVBobby VigilApr 27, 20172.0Only reason I give 2 stars if for the few great customer service reps they have. Other than that I dislike everything about this bank. Let's start with some of the reps at different locations that make me feel like my businesses inconvenience to them. Sorry you have to do your job? There aren't any available reps after hours via phone like most large banks (24 service or at least weekend service). I have troubles on their website constantly. Won't tell you the charges made because of the way is listed. Shows pending charge, atm, debit. ... would be nice to verify the charge. And I've tried on the desktop as well as ipad. Same results. Running balance only allies the several charges, to a few days previous. So basically when you switch to previous pages it doesn't show your balance at that point in time. ' You do the math here 'is my understanding of it. Last, I've been locked out of my account for making several large purchases (under $1000) in a day, Christmas season. It was a Saturday. Luckily I had cash saved because I was unable to use my card until the next business day when I could reach them. A phone call would have been nice before locking my out. Very frustrated w this bank and will be transferring very very soon. Hope This helps.
