FNB is the worst bank to deal with really

this is the worst bank to deal with really, I was with another bank for years and now with FNB due to recommendation from a friend and it's not making the pots tu,

I called to check if the money I sent via EWallet to someone is still there as they are not getting it, it keeps saying error at the ATM now I cannot be authenticated via app cause I do not have it 2 they cannot authenticate me on cell phone banking that I used to send the EWallet as it gives an error on their side saying something about swim swap which I never did on this number I'm using the number I got when I bought the sim card ,listen to this I need to now go to the bank for authentication because their system has a glitch ,I'm using the cellphone banking while talking to them. the one is saying I'm going to put you through to cellphone banking to assist with fixing the error rq***, and they transfer me to second one and she said no that error can only be fixed at the bank rq***, so the right hand is not communication with the right one it's a mess ,the last complaint was responded saying I was contacted by the bank which was not true ,so I would not be surprised if it happens again
