Not doing anything to help a person

I wrote a review about two months ago regarding a cheque account being opened in my name that wasn't mine. I got feedback via email saying that the account balance is going to be written off and the file is going to be closed with a reference number. Up to date I get phone calls from standard bank pre legal department to pay the account witch has now become more and eveyday I expain the situation to them and send them the email I received and the reference and everyday they do nothing about it. They are keeping me from doing my job and from my sleep after I worked a long night night shift it is really getting ridiculous and very time wasting going over the same thing day in and day out and nothing is being done about the problem.
