Pathetic Service

i have been an fnb client for many many years. i have recently taken out a loan with them. My salary gets paid into my bank account on the 29th of every month. Each month the loan amount goes off on the 29th.The amount of R2060.84. This evening i get a sms from Fnb stating the following. "The debit order to repay your FNB loan of R2060.84 was unpaid on 2017-09-28. You bank acc has already been charged penalty fees.Call ********** 091 for help." i am totally disgusted by FNB service delivery.i have been a client for so many years and they know i get paid the 29th of every month. They send me an ugly sms like this is pathetic. i am thinking of moving over to Standard Bank or Absa. i am shocked with this pathetic service.
