New business account locked due to "SOMETHING WENT WRONG !!! "

I decided a short while ago to open a business account with Capitec Business. Everything went smooth from opening the account to receiving the card. I activated the card and created a digital id as requested by online banking. I paid money into the account to activate it. I cannot log into the banking app or online banking. I get constant messages that "something went wrong" or "authentication failed" or some other nonsense. When I get an OTP, it arrives through sms and email and is not the same number. If you enter either or, authentication is failed and after trying my login/password/digital id/username, the account is now locked. This has left me with zero confidence to trust my business money to be paid into this unreliable account. My son also has a new business account and he has exactly the same issues. Thank goodness we have not started using this unreliable bank account or requested our customers to use the new banking details, otherwise our money would be stuck in a locked account. And please dont come with "visit the branch stories" I do not have the luxury to go and wait for service, I joined online, I expect to be helped in similar fashion.
