Credit reporting, credit repair services, or other personal consumer reports complaint — Experian Information Solutions

I notified Experian of an inaccuracy on my report by national credit adjust. This same account was reported to Experian by another company, XXXX XXXX XXXX XXXX which was deleted on XX/XX/2019 because it was proven invalid. Experian created what they called an investigation which lead to the incorrect/fraud info to remain on my report after they deleted this same info by another collection agency previously. This information is completely false and should not remain on my credit. Please help!
