The new bill stops that. Now, a debt has to be at least 60 days late before a company can raise your rates. This is a big boon to the consumer, and will cover simple mistakes. However, I would expect those rate increases to be bigger now, as the credit companies will be protecting against default more agressively.
One thing I can tell you is this: It isn’t going to last. Either you will cure the problem, or you will eventually just run out of credit problems. Either way, the problem will get solved.
