Honestly, I do not care for Lexington Law. I had them help me several years ago and all 3 credit bureaus rejected their letters. I got copies of the letters and it looked like a 8th grader wrote the letters and they forged my signature, which raised a Red Flag with the bureaus. 
I wrote letters on the professional level than Lexington Law and had those items in question removed or updated. If by chance you use them, ask them to send you the letters before they send them to the bureaus and if they sign your name on those letters, that may cause a problem 
of fraud unless they get a POA. This Is just my opinion and my experience with this organization not until I met Hack Man that help me solve all my credit issues. However, if your in U.K, US or Australia, I know a really good credit specialist that will fix your credit to
get you approved for a home loan, mortgage loan, medicals and many more...He has connections at all 3 credit bureaus......Contact him: Jonathanjamescyberservices@gmail.com text(209) 317-0582
