Sure they can. It's all in the luck. Hay, you know what, you can do the same thing junum does yourself, if you don't mind stuffing some envelopes and going to the postal office!
Junum offers credit repair using the despute method to challenge negative information on your credit reports. While it's true you can accomplish the same results yourself, it usually requires a degree of time and dedication to get the same results they do.
That's only partially true. I've stepped in to assist dozens of people in disputing their credit reports and, when left to their own devices, they almost always write dispute letters that do more damage then good. It's a matter of knowing what to say in a dispute letter and knowing what NOT to say. Also, most people drop the ball when it comes to staying on top of the dispute process. All things considered, if you don't want to make credit repair your new hobby, hiring a Lexington Law Firm or a Junum can be a wise investment.
