72 hours turnover

Discovery bank ended our relationship last week Thursday and I was promised my money will reflect in 72 hours . I did send all the documents they asked for. Even now my money is still not reflecting. I haven't paid my rent also kids are going back to school I can't even buy them lunch or uniform. They won't be able to go to school until this bank gives me my money. Everytime I call I have to authorise the call on my app and I don't have access to it . This is really heartbreaking
