Charges R840 for cash deposit fees

Last month I complained about absa rediculous & high banking charges and was told the the charges were for immidiate payment eft's where I was charged R850. Today once again I got the schock of my life when I was charged R840 for cash deposit fees. Last month i asked for a detailed statement of how the charges were calculated and never recieved the information I asked for instead I was given an ultimatum that I either accept 50% of what i was charged back or there will be no further communication. I asked how I could prevent further high charges & i was told to stop doing immidiate eft's & that Absa convinience does not come cheap. So I stopped all immidiate payments, but now they have found another way to milk money out of me. Should i now ask people to stop depositing money into my cheque account to avoid these hefty charges as well. I stopped using my savings account as i was avoiding all R99 ****s and absa advised that a cheque account would be a safer & cheaper option. Only to find that it's not the case. i pay a fee of R169 per month which I have signed for but I have all these other admin charges that I know nothing about. Please assist with this matter urgently as I cannot afford absa monthly ****************, this is seriously getting out of hand. Absa is robbing people.
