Nedbank Customer Service is horrific!

Just had the worst customer experience with Nedbank. I had an issue with the Nedbank Money App not processing "Approve-It" messages. I went to the branch at The Gove Mall in Pretoria, as advised by the app message. The staff were incredibly unprofessional (uniforms soiled and having private conversations in front of customers) and the ticketing system was also not operational. While waiting for 60 minutes + to get served, I overheard an extremely annoyed customer who urgently needed forex, being rudely informed that the request cannot be serviced at that branch (after apparently having been informed telephonically before hand that he should come to this specific branch for assistance). When I finally got to an assistant, I was told (again rather unprofessionally that she experienced the same issue as me, and that she still doesn't know what to do about it.) She then resorted to sharing my phone with her colleagues while they all tried to figure out what could be the issue (selecting and changing settings on my phone without telling me what they're trying to achieve). After about 20 - 3 minutes, out of desperation, I offered to rather call the help line from home, and see if they can assist, an offer which the staff eagerly accepted. Back at home, I managed to get through to an agent who also tried to correct the issue without success, and then requested me to reboot my phone, and then have her call me back in 3 minutes to see if the problem persists. 30 minutes later, I am still waiting for the return call....
