Poo Service

What terrible service from Nedbank How can nobody tell you why they are not debiting the correct account when you have given them a debit order instruction and banking details 3 months in a row. I have a personal loan and up to 4 months ago I called to change my banking details. The first month they continued to debit the old account and I thought ok it's the first month let's call and confirm again. When I called to say no payment has been made and that I’ve changed the debit order bank account they do their thing and confirm it will be done off the correct account the next month. 4 months later they keep taking money from my old account which is with another bank and an overdraft account putting me in a negative balance and me having to pay charges. I never receive messages to say my loan installment was not received . One month they debit the old account the next month nothing happens at all. At random times of the month they just debit my standard bank account and take from whichever money I have in my cheque account without notification, SMS or an arrangement. So due to an error on their side I am penalised making me short for the month. Then next month nothing happens. When I call I go through this whole process to change banking details again . Yesterday was actually the 5th time . I have literally done everything I could as the lender And then month end comes and the same thing happens. Mind u all the calls I make is at my expense and each call lasts for like 15-20 minutes. As a Nedbank customer for years this has been the most frustrating experience I've ever have with the bank. I will be moving all my services back to standard bank. I don't even want to speak to anyone further, the poor service is just unbelievable. .
