Disputed debit order.

I have tried to dispute a debit order that was not authorized to go off from my account, went to the local branch, apparently they also "cant " stop it or reverse the money to me, called the call center, where I was advised to fill out a Avidadit, went in to the branch again, with supporting documents, and still no joy, so the consultant just told me to open another account to prevent it from happening again. Money is being ****** from my account, and then the bank, just pulls up their shoulders... Very poor service indeed..
