I know a company that specializes in boosting credit scores, they're called “Hack Mavens Credit Specialist”. A friend of mine hired them 2 years ago, and recommended them to me. they helped me boost my credit score from 416 to about 785+ across the 3 credit bureaus in less than a week, I was surprised.
