Nedbank -Personal Loan Service

Hi , I would just like to highlight how frustrating it is to deal with the Nedbank Personal Loans Department , I recently took a personal loan from Nedbank assuming since I have a account with them everything will go smoothly , 01 April 2019 no debit order goes through , while I keep more than is required for the installment in my bank account , phone several times to move the debit to 01 May 2019 no response , I as the consumer should not bear the mistakes of Nedbank , there irresponsible lending practices need to come to light , I WILL NOT PAY THE ANY EXTRA INTEREST FOR THIS MONTH due to THE NEGLIGENCE OF NEDBANK , too quickly the banks give out the loans but fail to do a simple debit , please Nedbank its time to get things right ......poor customer service .....tired disgruntle client
