Providing fictitious deals to the bureaus then refuse to correct

I found out that I was overcommitted due to a non-existent BMW Finance R3 023 712 deal or account that was picked up or provided to Experian, which I miraculously have with them. I have been in communication with BMW Finance for almost a month and have interacted with 4 customer service reps thus far: Sibonakaliso, Mbali (who managed to assist by requesting a manual amendment with the bureaus), Mikayla or Michaela, and, lately, Senzo. Experian has since requested someone from BMW Finance to provide the correct open balance (or R0) by manually resubmitting via the CBA portal. To this day, there has been no response from anyone at BMW Finance, despite my several calls and emails. Customer service sends me to legal, legal to late payments, late payments to dealers’ support, and the cycle starts again.
