Nedbank App USELESS

I've opened a Nedbank account 2 weeks ago @ the N1 City Branch & cannot used my app. Every time I need to change something like a limit or pin etc. I need to visit the branch (how convenient)??!! I went to the ATM to change my pin. Phoned customer service to increase my limit, but apparently there's an incomplete task that the N1 City Branch did not complete on my profile & yet nothing can be done! I went to the Montague Gardens Branch yesterday & they also do not seem to know what to do, so I just left, as this is insane. Nedbank please up your game & teach your people to complete or do a proper Job! I need this sorted ASAP! Thought I went to a better bank, but eish seems to be worse than the previous one! I cannot go into the bank every time I need a transaction to be made! I mean why do you have an app if it can't be used! This needs to be sorted without me going in yet again, as you are *********** to say the least!!!!
