I agree with MSSMITH.
I'm a government regulator in another state and another industry.
Some businesses know how to work the system. They will milk the system for a few dollars more. Most will wait to the last minute, when they feel the hammer is about to drop, they take care of it. Or, when the customer is about to file paperwork, miracle of miracles, here it is, sorry for the delay.
The business will say that an employee screwed up or they lost the paperwork or some other excuse. As a regulator, I will let someone get away with this kind of nonsense once or twice, depending on the severity. Some blatant cases take immediate action. I will document the case, either way, usually with a Notice of Violation (kind of like a warning ticket). That way, when I take enforcement action later, I will be able to show a pattern or prior history.
In the administrative regulatory world, there are two sides to the coin. On the one hand, we are the overbearing government stifling a man trying to make a living. On the other hand, we are trying to protect the unsuspecting public. If this is the first case filed with the agency, they almost have to give the dealer a chance to make it right.
If the business has done this 100 times, it doesn't help a case if the public has not filed a complaint. I recommend that you proceed directly to the government agency that regulates dealers.
Good luck.
