Wrongfully black listed

When I check my credit report at Transunion I found that there is a Nimble account that I don't know. I contacted the Nimble and they told me is the Capitec debt. I said I do not about this debt it was previously investigated and failed to prove that it was mine as it might have opened **********ly. So Nimble just take this debt without contacting me and send this information to credit bureau without verifying this information if it's belong to me. The worst thing is that they were quick to send the information to credit bureau and never updated it. Can you remove your account from Transunion credit bureau as I did not went to Capitec and app**** the loan and this matter was resolved to my favour as failed to prove that i am the one who opened this account. Then they decided to sell this account to Nimble.
