Wesbank stating lies on my account

I took vehicle finance with Wesbank, in 2016.My ID number is ***. I couldn't afford to pay for the car due to liquidation of the company I was working for, my car was then repossessed, i then later received a statement from Wesbank that i owe them R163000, i asked for a statement so they can show me how they got to this R163000 and i received no such correspondence, i then was called by a company called vericred as a collection agency for Wesbank and they stated that i can pay in banking details that i 2was emailed, i have been asking both wesbank and vericred for a statement as i feel it is my legal right to know how they got to the amount they are stating I'm owing them, i have not received anything, i have just been bul**** into paying because I am scared I will be blacklisted.i have had no response from vericred or Wesbank, i dont even know whether the banking details i paid into are valid.
