Treating customers fairly

I reversed a debit order using the app, after processing it was successful and gave me information that it takes up to 2 hours to reflect. After 2 hours,I checked the app, no reversal was done so I called the call center asking them on the progress. Firstly the system was down and secondly I was given a turn around time of 24 to 48 hours. I asked the agent why did the information not appear on the app. The 2 hour TAT was apparently only applicable during office hours, because I did it after business hours so I have to wait 24 to 48 hours. Firstly the difference in the turn around times is mind boggling and secondly this information should have been displayed on the app. Nedbank have falsely advertised the turn around time on the app. Where is the transparency!!! This is absolutely shocking and I will be taking this up with the ombudsman as a matter of principle. This a shocking display of not treating clients fairly. Firstly false information and secondly to be answered by a rude agent who gave the information like it was obvious when the app had contradictory information!!!! I hope all are aware of how putrid this service was from the app to the call center. Pathetic!!!
