Bad service

I feel like im in an abusive relationship with this bank. Last week i opened an aspire fusion account on their app and deposited money to activate the account. I then sent the documents their required but now my account has been frozen and i cannot access the funds. I have reached out to them via their secure chat,emails,call centre and facebook since last week with no joy. Im so frustrated and so inconvenienced. They keep on saying it will take 24hrs for the hold on my account to be lifted and its been more than 72hrs now
