wrong person on settlement letter

I have been struggling for a year to get hold of someone from Standard bank to help me. however I have been transferred from division to the next.<br> In December 2014 I settled my car, I got a settlement letter from Gopane Pauline stating my car is settled, the ID number and account number is correct on the document but the customer name is another persons. Since then I have not received any other documents. when I call the vehicle finance number they say they cant help me and that my vehicle is in arrears and they cant help me.<br>
