Incorrect Bureau Data Feed, Affecting my score

Despite the multiple other issues I have had, the most frustrating one is incorrect bureau updates. I checked my profile and to my dismay my information on my loan is incorrect. The account is up to date yet I am still getting harrassed with daily phone calls and notifications. Worst of all is my bureau report for June is reflecting incorrectly and was updated prematurely. As at the 28th June the report for June was reflecting an incorrect balance, oustanding amount and payment status. I need this updated as a matter of urgency.
