However, I received a notice of parking offence the very next day - for parking without a valid parking ticket.

I had to take another day off to go to the branch office, where I learnt that it took a day to update the system. As the branch-office staff knew that one day was needed to update their system, why wasn't any action taken to avoid such inconvenience to ticket holders?

They could have issued a notice for the ticket holder to display on the vehicle. This would have saved me from getting booked.
