Incorrect judgement on my name

The WORSE!!! BAD BAD service I had taken out a personal loan with Old mutual CRESTA after my account had been Handed over to MBD my Finances came rite and I asked MBD for a settlement amount and settled I even got a paid up letter but to my surprise I now have a judgement on my name but what confuses me the most is that this was fine after I had settled with them I’m so disappointed in the way all this turned out Old mutual is the worse organisation a person could even deal with and they are the biggest ******* ****** I will never do business with them again and will close my existing policy’s with them
