Forget the BBB! They are a corrupt and useless organization that has absolutely no power to do anything for you. Did you know that the BBB is a FOR PROFIT business?
Second, STAY OFF THE PHONE!! Phone calls and regular mail DO NOT protect your rights under the law.
ALWAYS communicate in any legal dispute IN WRITING and via CERTIFIED MAIL, RETURN RECIEPT REQUESTED, Always put the certified# in the body of the letter as this proves exactly what you sent. Keep a copy for your records.
By the means above, dispute their claim, refuse to comply with that stupidity, and DEMAND picture proof. Then re-attach your evidence, and re-send. Do a CC to the governor, DMV, and as many other applicable government agencies as you can think of. Also try contacting an investigative news channel.
These tickets follow the REGISTRATION of the vehicle, NOT the title. The registered owner at the time of the violation.
In my opinion, everything that is screwed up in this country originated in CA. Idiots.
