I was a BOK customer, called their # checked my account total( sure enough , just enough left). It was a tight month. I needed 30.00 cash & my receipt showed that a I had a couple dollars left. The next day they totaled up 3 26.00 over draft fees. Their excuse is, they don't show all the transactions till they process them. How come my additional electronic transfer didn't count. I sent 50 more over & it doesn't count. They just wanted to " screw" me out of 78.00. Bank of Oklahoma "now" manipulates their accounting times in order to process more over draft fees. I have a bank receipt showing , I had positive money in my account after my last withdraw. I'm still getting 3 overdrafts charged to my account. They are crooks! Greedy ! crooks!
