False Information sent to credit bureau

<p>My current credit report (June 2017) reflects that I was 30 days in arrears for the month of June 2016 on my vehicle finance account. </p> <p>This is false as the first debit order was only scheduled to be deducted in July 2016 which reflects on my bank statement clearly.</p> <p>The 30 day false arrears only reflects on Experian credit bureau, but shows no arrears on Transunion, XDS and Compuscan.</p> <p>I want the 30 day arrears reflecting under Experian updated, corrected and proof to be sent to me ASAP, as this negatively affects my credit scoring during this 24 month period.</p>
