Absa doesnt want to help clear my name from *****ulent accounts and loans.

A current account has been open under my full details at Klipfontein, Highland mews Branch in Witbank. This came to my attention around June this year when I purchased a vehicle with Absa asset Finance. I did not know I had a current account at Absa. When the account is in overdraft and arrears Absa starts harassing me to come and pay the amount. Further more it appears that the same person who opened the account at Absa has took out loans from Finchoice. All of this are affecting my credit score. I have tried to speak to Absa ***** department and I was told to send an affidavit and copy of ID. I did that,but they later said that my ***** case was closed because they cant get hold of me. Im working underground and I work strange hours. I need Absa to assist I cant be going through all of this because of the ***** that Is happening at Highland mews. How did the person open an account without my Finger Prints?
