Inability to close bank account

I have been trying to close my bank account for over a week and a half. The consultants really did try their best with even the manager getting involved. However the consultants were required to call central head office where absolutely no one could help. I have been into the bank three times with the same pattern. Very helpful face to face consultants but central head office providing absolutely no help. Both my frustration and the various consultants frustration has shown through. All I want to do is close an account, how can it be so hard
