If you find something on your credit report that you believe is incorrect, it is absolutely crucial that you act immediately, not least because it is likely to be having a negative impact on your score. In order to do this, you will need to contact the main three credit bureaus directly. They will likely ask you to submit some evidence as to why the information is incorrect. Once they receive this, they will be able to remove the entry from your report, and subsequently, update your score.
