Its a SCAM.
California Parking Company, who also owns Parking Control Service, is a SCAM.
Parking Control Service issues fake "parking tickets" to unsuspecting drivers. The ticket citation might look like a real parking ticket but if you read the fine prints, they are NOT government related.
They usually issue these tickets inside parking lots they operate.
Agents that issue these tickets are not trained in law, matter of fact, they can not legally enforce public parking regulations. These individuals are often high school drop outs with no skills. California Parking Company takes advantage of these individuals to scam the public.
Watch out! If your ticket says Parking Control Service on it, it is a private company. Do NOT pay the bill.
