Diamond Parking Service Spokane Washington review: Parking ticket

We are protesting the excessive penalty for only being ten minutes over our four (4) hour parking term, and we are protesting the statement on the ticket "No Advance Payment." (details below)

We parked and paid four (4) hours parking for our Subaru Outback license plate K613912 in Lot Code B217 at 2:45 pm on Aug. 16.

We have a "Parkwhiz" payment of $10.71 prepaid parking authorization #[protected] for that four (4) hours of service.

The service ended at 6:45 on Aug. 18, and we received a ticket for $46.50 at 6:55 pm - exactly ten minutes after our time expired.
