I was contacted by this company by a Mr. Barnes in reference to a debt owed to former landlord/rental agency after vacating the property the previous year. The debt owed increased by over $1200.00. I was advised if I felt the debt was not owed to supporting documentation, but Mr. Barnes hung up on me before giving me the proper address to sent complaints too. He continued to call daily, multiple times, and when I asked for a supervisor, I was hung up on or put on hold for 30 minutes or more, only to be rerouted to Mr. Barne's voicemail. I advised him on another occassion that I was a student, and he actually threatened to garnish Federal Funds, and when I advised him that would be a federal crime, he hung up on me. He contacted my mother and when she asked for something sent via USPS, certifed mail, he hung up on her. I found their mailing information through the Federal Trade Commission, and sent 17 plus pages of supporting documentation, and when I received another call, this time from Ms. Bennett, she had no idea what I was talking about. When I asked her for a supervisor, she hung up on me. They have threatened that they will assure I will not be able to receive federal grants for a public/state university, and when I informed them different, they hang up on me. They overtalk, yell, and make threats and seem to have no reasoning, ethics, or communication skills. After I searched the internet, I found 1.8 million hits and complaints for fraud and scam alerts in reference to National Credit Services. Any attempts to dispute the claim, end in them hanging up on me. They sent threatening information to my grandmother, and spelled her name wrong and got the address wrong. They say you can dispute the claim, but you really can't. It seems I am only one of many thousands of clients being abused by this company.
