My advice is to only hire LL to dispute debt that is not valid or correct, If you pay them to dipute sorrect information,Even if they do have it removed the chances are they will reappear as validated and be put right back onto your report.Disputing debt that you actually incurred and allowed to be sent into collection is a waste of time and money,If you own the debt,save one hundred bucks a month and try settling and PFD letters.
