I also have an issue about a late payment that was reported to the credit agency. I was unaware that i owed the money and upon notification, I made the payment immediately. Now it appears on my credit report. I called and asked to speak to a supervisor in the credit reporting department (FIOS) but the supervisors have been too busy to speak with me or call me back.
