Poor customer service. Useless national helpline

I received my new card in June - had to hand over my ID. I've had mails and SMSs to update my FICA info - I've rep**** to those mails with the relevant requirements. I tried to FICA on my app but no go. They block my account on payday. There is no local number for the branch so I call into the national help line - needless to say the story is only the branch can assist. Which is closed. It has been 5 days and still nothing from them. I've now been in to the branch 4 times - each time closed with no ETA. The call centre operative tells me it will be open on Sunday (to make up for the closure) and makes me an appointment. Guess what? NOT. OPEN. Shocking shocking service from a bank. I signed up with another bank who FICA'd me via my phone selfie in 15 minutes. Needless to say, when I eventually get my account unlocked, Nedbank won't ever see me again.
