Registering a Vehicle: Vehicle Registraton Includes Parking Ticket Fees

My question involves vehicle registration or title in the state of: California

My vehicle registration fees include a parking ticket that is not mine. It has been determined that they transposed a digit on the original parking ticket and the ticket should never have been assigned to me, but the ticket fees are on my vehicle registration. DMV is no help, they say that issuing entity must remove the lien. I have contacted the Parking Enforcement numerous times. They say that they will remove but do not follow thru. What can I do?
