Left with no access to money with no warning just before payday :'(

On 24 Nov, I got an sms and email from Discovery bank: "Until we can verify some of your information, we've limited your account functionality. We'll email more details. Or you can call ***" I was waiting for an email but logged into my banking app and all seemed normal. Until i went to the shops and my card was declined. Then i phoned the number on the sms to see what they need. I was told that FICA expired on 23 November, yesterday and now my account was blocked! On 25 Nov, i finally got the email with the details they need. i promptly attached the details, but cannot print the form, so i responded to the questions in the email body. I got an automatic response. today is 27 November, I have not had another responce, but my account is still blocked
