Really Pathetic Service

FNB i am really receiving pathetic service from you.... i have been a client for more than 20 years.... on the 28 September i received a message that says the following "The debit order to repay your FNB loan of R2060.84 was unpaid on the 2017-09-28. Your bank acc has already been charged penalty fees. How can you charge me penalty fees if i only get paid the 29 of every month. To top it up you guys called me earlier this week saying that my debit order will be going off the 15 December. Today i get a message saying To keep your personal loan account up to date and peace of mind your debit order was processed today. i am not impressed with your service one bit. I am going to move to Standard Bank.Why do i have to pay penalty fees this is not acceptable. Sorry FNB but i will take my buisness elsewhere your service has become pathetic really.
