Getting anything done with this bank is miserable and I dread every time I have to hold 20 min for a simple question. They also dont update balances on the weekend accurately and the card declines when you are trying to pay a bill, as the app doesnt show the balance. I have been a WSB customer and since the merger features and services have been removed or gone backwards. This review is O2 as a whole not anynone branch
