Debit order ****

Every year inDecember, FNB sends out notices that Debit orders will go off earlier. From about the 15th of December. And every year I have to secure chat with them to change this as I am only getting paid (Like every other Month!) on the 25th and as per our agreement, Debit orders should only go off on the 25th. NOW they have take R1100 for my vehicle insurance out off my Holiday Money!!!!! After I have requested them NOT TO. If you think about it. 100 thousand clients who pay their debit orders 10 days earlier, how much intrest do FNB make with OUR MONEY....
