No Consent credit check

Somebody calls me that they're updating information on the system, I told him NOT to submit an application or do a credit check on me as i am busy sorting stuff out at transunion. A day later i get a notification of MFC doing a credit check on me. I called MFC, some lady at new business enquiries named Emelda says it was the dealer who submitted an application. I called the dealer and they deny this. I called MFC again and they referred me to their dealer relationship manager , Joan, who has been helpful. She found out that audit called me and it might have been a system glitch that a credit enquiry was done. I called new business again and they CONFIRMED that an actual application was submitted by someone from audit, cleearly someone is lying to me to cover up. What i dont understand is that i spoke to 7 people from MFC and none of them acknowledges the fact that despite the application declining, the credit enquiry has dropped my credit score even further down and I DID NOT AGREE to it, what happened to consent ? NCR and Ombudsman is my next stop, i want MFC to remove that enquiry and delete that application on their systems like it never happened
