I doubt regulations address what happened to you. The banking industry pretty much owns the agencies that regulate it and their people write the regulations. Yes, banks will "correct" those problems if someone calls and is persistent enough, but they (and the credit industry) know that plenty of people won't notice or will figure they can't do anything about it. Regulators exist only to make it appear that the system is honest and it isn't just banking; the same can be said about insurance, nuclear power, nursing homes and other regulated industries. Big business has little to fear from its friends in the regulatory agencies and, in the end, the only thing that keeps things (mostly) honest is the cost of being sued. The regulators are content to beat up the little guys.
