Nedbank - Misleading clients and lack of respect for their clients time

Nedbank customer service is putrid, clients are encouraged to stay away of switch banks. I have been a loyal client of theirs for 15 years and the service i recieved from the contact centres were disappointing to the least, from being misled by managerial staff of their contact centres to being **** to about the turn around time they would be contacting me in. These people have no respect and decency for another persons time, all for a simple refund that was supposed to be filed 5 days ago only to find out that they didnt even process it until i called them 2 days later to follow up
