Frustrated Customer

I am beyond frustrated at this point. I sought the help of Nedbank regarding the Nedbank Money app. First the app wouldn't allow me to conduct transactions. That problem was resolved, a few hours later I cannot log into my account to run transactions with a irritating "error user state" feedback message. I have been to Nedbank branches yesterday and spent the majority of my day trying to rectify this. The transaction component was fixed but I am beyond upset as it seems I'm encountering a new problem everyday with this app. Now trying to call the call center for assistance I'm hit with a stumbling block because the call is not toll free and I can't enact an airtime transaction to resolve my issues as the app won't process a thing. Can someone at Nedbank please just take 10minutes and tend to this matter or I feel I'll close my account and take my business elsewhere.
