Ridiculous customer service @ Nedbank

Worst bank ever. I opened my account with Nedbank in November 2019 and they put a hold on my account without notifying me all I saw was the app not being responsive. I then went to their branch in Overport, Durban to tell them that i cant do any tranfers from the app.. they figgled with my phone, told me to delete the app and restart the phone... eventually I got tired of waiting and went to try withdraw from the ATM... I went out and obviously was not successful... I then went back inside to tell them that I could not make a withdrawal. It was then when I was told that there was a hold on my account... I asked them for the reason on the hold and they could not tell me... i was told that it would take an hour or two for the hold to be released... I then got called about am hour later advising that my account was ok..I missed an important payment and Nedbank made me do the run around and could not tell me why my account was suspended.. I did not expect such an unprofessional response from such a great brand.
