Sent to court twice for 1 car

I bought a car with the standard bank in 2013 and in 2018 I lost my job was unable to pay. And I have tried several means to get assistant from the bank only to be summoned by their attorneys and I gave the car over to them not that I was not paying its only that I was paying less than the initial instalment. And worse is that these attorney they never inform me of any court dates. And the car was sold at an auction still was not informed of the auction date and place and I checked till I found out which auctioner sold it but the car was not sold with all its extras like keys and carport. And still recently I have a judgement again on the same car with a diferent amount and date but nothing was sent to me to be able to go to court and have my faith. Right now I'm unable to get employmenr because there is a judgment on my name twice for 1 car. How can that happen.
