It's false information though, if the person hasn't opened an account. It might or might not be negative based on what the recipient of that information deduces, but it's definitely false.
The problem would be intent: my understanding is that in the U.S. at least you would have to show that they knew it was false when they published it or refused to correct it. If they simply say “technical error, we fixed it” I think your odds of reaching that bar would be quite daunting.
