If you have a direct dispute and the dispute is found to be accurate, there would be no record in e-OSCAR for that dispute to be on their report, you would be responding to the consumer directly. We have maintained a log since 2004 and it's really easy to maintain. These are the columns:
Dispute type (e-OSCAR, Letter, Verbal)
Response (Accurate, Modify, Delete)
Comments (Not same person, 2nd dispute this year, etc..)
Our deposit department also records any Chexsystem disputes on a separate log maintained in their department.
