Rediculous Price Rate For Parking

My manager Alvin Prithipaul, has recieved rather shocking service fee from the OR Tambo airport.How is possible to be charged R1860 for parking from 04:37 06/03/2019 to 17:02 07/03/2019( One day)!!!! This is not acceptable service ********** ********** received the Airport. After trying to have the matter resolved Pumeza ****o insists it the correct rates. How can open parking cost more than total trip
