I have a dispute with equifax and when I checked online it said the due date was 03/02/03 now is shows the start date of 03/02/03 and a completion date of 03/05/2003 WTF!!!!! how can that be....
We have one like this too - it was a current address dispute opened 2/25 due to close on 2/28. Guess they are getting faster lol Wish I had a good answer for you!
When the dates change like that, it means the investigation is complete and they are updating your report. Most likely they are making changes, which usually is a deletion.
Go into the Eq dispute screen, use the confirmation number that was given when you entered the dispute. If the dispute is finished, it will show your results. If not, it will give you the start and end dates of the dispute.
