*****ulent Account opened in my name

A *****ulent account was open in my name and mtn requested i do an affidavit and send a copy of my certified ID which i did and said they will clear my name. This occurred in 2021, i went to mtn's offices to request a letter of confirmation that the account was fradulently opened, and to also requested that my name be cleared in their system as a none payer. I called nimble to inform them about the situation and provided all necessary supporting documents as evidence despite all the effort made nothing happened to this day. Nimble still appears on my credit score that i owe them and this has negatively affected my credit score as now I'm labelled as a bad payer because of Nimble's incompetency to resolve the matter that has been pending for more than 2years.
