Propark America West

I decided to park at the Gallery for 2 days. Their website says clearly that parking maximum per day is $12. I saved the web page for reference. http://www.propark.com/propark-locator/ now says 30. It said $12 back in June when I parked. I complained using the online contact form, and I called the local number. No response and no call back. I still have the website cached which proves the cost is advertised at $12 then changed sometime within the last week. At best misleading, at worst fraudulent If you want the webpage I saved, I still have it for your reference.Product_Or_Service: ParkingOrder_Number: [redacted]Account_Number: [redacted]Desired SettlementI want to receive the difference between what I ended up paying and what I should have paid. I paid $48 and should have paid no more than $20. I should get AT LEAST $28 back.
