Litterally cannot open an accout because of bugs

I've been trying to open a Capitec account as a secondary backup account and it's basically impossible. They created an account and sent me a card, but I can't log into it or use the account in any way.

Opening the app says I need to go into a branch to finish my registration (which they said I wouldn't need to originally). I go into the branch, they capture my finger prints and such, and the couldn't get the mobile app to validate because of a bunch of bugs on their system. Now I can't phone phone them because they say my phone number is invalid and they just hang up on me.

They apparently had enough verification to open the account and send me a card, but they can't verify who I am even when I go into the branch, if this is the kind of experience I should expect from the bank, then it's just not worth it. I was able to open another account with Discovery in like 20 minutes, everything works.
