Very very bad service for the financial institution that says they are more than just a bank

I have requested Standard Bank to deregister my car that has been written off in April 2017 and got the shock of my life when I found out on the 30 Apr 2018 when I was renewing the license disc of the other car that written off car has not been deregistered. For the dept to release the disc of my car I had to pay renewal fee for the car that was supposed to be deregistered by Standard bank in 2017 April already. I complained on this platform on the 30rd and Standard bank responded assuring me that this will be addresses as a matter of urgently even today, I still have not heard anything from Standard bank .
