FIX this NONSENSE URGENTLY!!

Attention Micheal Bruintjies Helpdesk Administrator from Nimble group my name is Wandile Zimu, I previously had an account with ABSA bank years back from now & had taken a loan way back in 2016. I was therefore handed over to you guys but however I managed to settle my account in 2018 & had sent you a settlement letter only to find out that this year Nimble Group has added my details on credit bureau with Trans Union & therefore I'm unable to apply for anything. I have tried making contact with Nimble Group with no success & have also logged a ticket through my e-mail with the settlement letter attached only to find out that your response is "Your ticket - Settlement letter - has been closed" with no other explanation to this & no other form of communication from Nimble Group!!!! Yesterday a consultant even called me & I had to explain this matter again for the 100 times now please can you guys remove my name from credit bureau and please contact me to let me know that this matter has been resolved I'm tired of this nonsense & running after Nimble Group to do their DAMN job properly!!!! This has caused constant fights & arguments with my wife please fix this issue as URGENTLY as you can!
