Pathetic Sevice From Nedbank Insurance Service Centre

I have been on the phone for an hour this morning with Nedbank insurance client services. I took up a personal lines cover + building and set to pay via debit order. I updated bank details on 11/11 and got confirmation that the change has been effected on 13/11. Yesterday Nedbank debited an incorrect account because Candice Carpede future dated the change to December instead of November. Spoke to Sharon Makikita who refused to escalate my call to a manager and ultimately blindly transferred me to complaints without explaining my issue. Appalling service! Not happy at all with firstly, not being accurate when updating information and secondly, the poor client experience i have had when dealing with Sharon. I have been with Nedbank for donkey ages and the service keeps getting worse with every interaction i have with your consultants. Get this nonsense in order!
