Horror experience

So I opened a Nedbank account with high hopes of switching my salary to them....yoh what a horrible experience....so here is my story : I wàs assisted by a very friendly guy (Ntsako) at their Quagga branch and everything ran smoothly.....untill I went home to install the app....with constantly gave me an error (Authentication failed) so I consult with their Facebook team which seemed to have no idea of what they are doing coz I was told to activate by depositing some money which I did a while ago after just opening the account.....xap I went to their Atteridgeville boxer branch where I was not assisted and told to call their call center number...I was on the phone for plus minus 45 minutes being transferred from on agent to another....the last person told me to visit a real branch not a boxer one...xap mind you now the app can't even open is just stuck and everything seems not be working....I went to Atteridgeville branch I stood outside for 35 minutes untill the security personnel allowed us in....the que ticket lady tried helping but failed then gave me a ticket...my ticket was eventually called after 23 minutes,then I went to the teller/consultant who even asked for my ATM pin (wow) we deleted the app then installed it again while she gave me a lot of papers to sign.....I was there for 2 hours and still my app is still the same....the lady after two hours she sent me back to the ticket lady....by the time I was late for my shift...so much for a bank bank that takes money choices seriously...hello I'm here having an account with a bank that have people who can't resolve small issues like a mere app....I'm still sitting with an app that is not working wow
