Very Poor Service

I raised an issue with Nedbank regarding their mobile banking app. Since I opened the account I cannot enrol for the app, I have visited the branch countless times, I have called their customer care line, I have used their web chat and all I get are automated responses or I get transferred from pillar to post. No one seems to have an answer or even an apology. I get a reference number but when I follow up no one gives me a response. Very poor service from Nedbank
