High bank fees on zero account and cheque account

Fnb does not help me to safe my money as you busy messing up my account with bank fees. My easy zero account is on -R296 what fees are they? My cheque account have been charged with R100 for failed debit order which I asked fnb to stop it.

If you guys u will continue on charging me like this then u will stop using this account as I'm currently unemployed.

How can I afford to pay so much fees?

I feel is unfair
