True, you can be refused credit even on the strength of the Banks own mistake.
That's true but I've never had it happen. I've been monitoring my credit for about 5 years now. The only thing I've had to do is remind the credit companies of positive actions on my part. They are quick to ding you and slow to fix or update your score. One is just as bad as the other. I hate the whole credit system. You have to use it, spend money and monitor it in order to build it. Without REALLY good credit, loan rates SUCK. You have to spend money and use the system in order to make it work in your favor. Just earning a good living and being responsible with your money isn't enough.
