Standard Bank vehicle finance

Last year September 12 I had my car ******. My insurance paid out and I paid the shortfall before end of September. I have been trying to get this account closed on standard bank side so I can deregister the ****** car, this is blocking my other vehicle for a disk registration. I have spent countless hours explaining to various standard Bank agents my situation. Standard Bank insurance department really don't answer my calls, I have been transfered to them and direct calls they don't answer.
