Disgusting service at Nedbank

i went to nedbank at New Market on Saturday for them to assist me regarding my New Nedbank App after all the hustle the lady who assisted me told me that i can start paying via my Nedbank App, Guess what only to find out that nothing absalutely nothing has been done to fix my App. when i call their stupid call centre still i am being told to go back to the branch coz they cannot assist me. It means Nedbank doesnt value me as their client i have been taken for granted and they have wasted my time money and petrol
