Hon Fee R90 ridiculous

Nedbank charged me R90 Hon Fee which I don't understand for a transfer I did on Friday the 3rd of R450.00. When I did this transfer my account was reflecting an amount of R738. I first did a R50 transfer then R450 , I was left with R238 after the two transactions. But when I check Sat my account is on - R100 and something???? There was now money deducted by pick n pay for transaction done sometime during the week don't know why it was only taken so late. No communication from Nedbank to notify me and when my husband give me some money Nedbank deducted this Hon Fee ridiculous the way the deal with me in this case . I should have been informed about this money not yet deducted by pick n pay or when I don't have enough money not showing me money while I don't have.
