Identity theft

I was handed over because 'my' Edgars acc was not paid for a long time. I dont have an Edgars acc. I went to our branch in town, when they enter my ID number there is another persons name linked to my ID number. And that outstanding amount is showing on my ID number. After several arguments the lady refused to help me, she said its not a problem on their side. But who signed for the goods that was brought? Where is the proof of ID when the account was opened? Im in a position now where I cant get financing on a vehicle because I am handed over. They refuse to help me. Its Edgars's responsibility to make sure that when an account is opened that the ID number and name of the person is correct. This is *****. The bank dont want to review my facilities or give financing unless the amount is not paid. I will not pay for something that I didnt buy.
