FNB CHARGES ME TWICE A MONTH ON ONE ACCOUNT

I JUST RECEIVED A MESSAGE NOW FROM FNB FOR REGARDING MY CHEQUE ACCOUNT, TELLING ME THAT MY ACCOUNT IS IN EXCESS. SO I LOG IN AND WHEN I CHECK, I WAS CHARGED<br> R135 SERVICE FEES ON 14 OCTOBER (MID MONTH)<br> R17.60 MONTHLY ACCOUNT FEE ON 14 OCTOBER (MID MONTH)<br> I DON'T UNDERSTAND WHY BECAUSE I HAD ALREADY PAID MY FEES AT THE END OF SEPTEMBER, WHICH WAS FOR THE WHOLE OF SEPTEMBER. SHOULDN'T YOU WAIT FOR THE END OF OCTOBER TO BILL ME AGAIN?<br> <br> PLEASE TELL ME WHY I'M BEING BILLED IN THE MIDDLE OF THE MONTH AND WHAT ARE THESE FEES FOR?<br> <br> I WILL NOT PAY ANY MONEY INTO THIS ACCOUNT BECAUSE THIS WAS NOT MY FAULT. FIX UP YOUR STUPID MISTAKES!!!
