Blocked account without warning

It is the only bank in South Africa that freezes customer accounts without warning. Calls and emails 1 week later reveal that they need documents. After providing the documents, they say that everything is fine, but the accounts do not work. After another week of calls, it turns out that they still need documents FICA, but they do not warn about this. After another 2 weeks, they need other documents. And so 3 weeks have passed since the accounts were blocked, and I am the only person in the family who pays for the house and all expenses for the family.
