National Credit Systems,Inc. Debt Collection Complaint

National Credit Systems,Inc. Debt collection department,

Other (phone, health club, etc.) Disclosure verification of debt Right to dispute notice not received Texas

Upon pulling my own credit report, I found out that I had an account in collections with National Credit Systems from a previous apartment complex. Upon contacting them, they were given no contact information at all to attempt to contact me. No phone numbers, no address, no reference phone numbers. Also no attempt was made by them to retrieve this information from the apartment, yet I am being told that this item can not be removed from my report because they made every attempt to contact me. What attempt was made? I contacted them as soon as I found out yet I am being penalized for their poor attempt at collections? I would like this issue addressed.
