I have requested they investigate several accounts that are being reported incorrectly. I have mailed letters on XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX. There are more dates but I feel this shows my attempts to work with them. My requests were to investigate and provide me details of the investigation. I requested them to delete the account based on they are reporting incorrectly. All I get is responses based on them submitting codes. No investigation ever happened. They have never provided me details of an investigation.
