Hon fee

I have a problem with my nedbank cheque acc which always seems to be overdrwan ...How i dont know because <br> i dont have any atm loans or overdraft .. and there is this hon fee that charges me +90 , i first saw it last month but ignored it and now it just appeared twice on my statement ..iam really not happy because i pay the monthly fee for the account but i dont know where this hon fee comes from ..im considering closing the account because this seems like a total rip of since everymonth i have to deal with an overdrawn account with extra fees that i dont know where they come from and all the time i hv to move my money from this cheque account to my savings account because im afraid of this charges .
