I disputed the debt from All-State Credit Bureau with the 2 CRAs that it was reported on: Equifax and Experian. Experian has replied to me, and the bad mark remains. Equifax has not responded, and their 30 days will be up in less than a week. I also sent a validation letter to the CA. They replied with information that conflicted with their original to me. Can I send another to Experian that includes the conflicting CA info., and have them re-investigate? Also, would you recommend sending out the "you haven't responded in 30 days" letter two business days before the actual 30 to Exquifax, to ensure they get it on exactly the 31st day?
