Regarding the 'correct information' you mention... I have never had a very 'active' credit history, I just don't borrow a lot. But when I went to buy my house, I pulled my credit report to see what its status was and do a sanity check. When I did, I found an error. What surprised me is that it was an error that was false on its face. It was an impossible entry. To this day I am perplexed how such a thing could exist on a credit report at all without being caught by even the most basic data consistency checks. It claimed, roughly, that on say July 2000 I had a balance of $0 on an account with a furniture company... and 30 days later, on August 2000, I was more than 180 days overdue with a balance of -$300 with that same company. Given that it is quite difficult to pack more than 180 days into the span of 30 days, I can only conclude that they just accumulate errors and do not value either correctness or basic sensibility.

Luckily I was able to easily get the error removed, but it seems absurd to me that a clear system error of some kind had simply persisted on my report for years.
