incorrect debit order date,deducting from overdraf

FNB debits my cheque account for personal loan on the 23/02 which was yesterday. I contacted them and they advised that my date is the 23rd , I told the agent that my paid date has always been the 25th for the past 10 years! <br> <br> she asked me about 10 times whilst looking at my records if my salary is received the 25th , I rep**** 10 x YES. I also explained to her that should the 25th fall on a Saturday or Sunday then I will get paid on the Friday.<br> <br> so yesterday they deducted from my overdraft, which I don't use as the charges are ridiculous, so now I'll be liable for that charges.<br> <br> agent emails me back and says they have on record that my paydate is the 23rd!!! I'm not going into the bank for a statement, I bank with them! are they not able to go back every month and look!!!
