I recently received a "Fine" from a so-called Private Car Park enforcement company, (Parking Enforcement Services) who are based in Perth WA. I parked in a shopping centre car park to shop at the centre. There was no infringement notice on my vehicle when I returned to it. I have just received an overdue notice from this company stating if it is not paid within 20 days more "further recovery action" will result at my expense. Further, if the fine is not paid and my vehicle is spotted at another one of their client's car parks, they will either clamp the wheel/s or tow the vehicle away. On a quick Google search, this company has no authority to do what they have done or what they have threatened to do. Is this correct?
